Check your fuel pressure ? Might bleed down when sitting.Other than that maybe TPS problem, vac leak, spark/coil.

I've got the exact same problem. My 5.9 has about 41,000 miles on it also.
I've taken it to the Dealer twice. The first time they looked at it they said it was the IAC solenoid. After replacing it it does the same thing.
The second time they said they could not reproduce the problem. LOL.
I've read several posts that suggest this problem may be the fuel pump.
Please let me know if/how you fix it.
Thanks

There is a blead off valve on top of the fuel pump. Sounds like that blead off valve may be the problem. I think you can replace it without replacine the whole fuel pump unit.

Try turning key on for a few seconds to let the fuel pump run. You should hear it run then stop when the pressure is up. Then crank it. If it cranks get the fuel system checked. On my '95 the pressure regulator is on the pump that is mounted in the tank.

Is the "bleed off" valve located on top of the fuel tank on late model Daks?
That sounds like a logical solution to the problem, since our engines run fine after they finally start.
Should the fuel system maintain a high pressure for a long time after the engine is shut down? Say for 24 hours or so?
After mine has been sitting for just an hour or so, there is no fuel under pressure at the Schrader valve on the fuel rail.
I have been turning my key to the "on" position for several seconds before I turn it over and that helps alot.

i know she cranks good but consider the battery and the pickup in the distributor.
if the pickup is dirty and it does get dirty, may throw out the computers initial sense of where the cam is,i clean mine once a year after a limp in condition started on my 93.
the battery, unplug the coil,put a digital multimeter set on volts across the terminals,as you crank the engine the value well increase untill 12 volt, compare how long it takes to reach 12 volt and how long you normally crank to get going. if its about the same. put a battery charger on the battery and crank the engine ,if it starts quicker your battery may be the blame.
be sure to check the connections on the battery and the chasis grounds. if you have a booster cable near by jump the negative terminal of the battery to the engine try starting again.

I'll try cleaning the pick up in the distributor.
Although I'm feeling like it is a fuel delivery problem.
I got under my truck by the gas tank and had someone turn the ignition key to ON. I could hear the fuel pump run for about 2-3 seconds then shut off. I then tested the Schrader valve on the fuel rail and there was no fuel under pressure there. I would assume there should be fuel pressure at the fuel rail after having the key turned on and the pump cycle to off. Any thoughts on this?
I tried to disconnect the flexible fuel line where it connects to the fuel rail to test for fuel pressure and flow at that point. I removed the metal keeper clip but could not disconnect the connection. How does it come apart?
Shirley, someone has had this problem and solved it!
Lets keep at it.

I had this exact same problem on my '98 318.
The problem is that you are loosing pressure in your fuel line. No matter when, where or how long, there should be pressure in your fuels lines. If at any time you go to the bleed valve, and depress it, fuel should spray out. Not just leak, but a good spray (for a short while anyways).
My truck was under warranty, so back to the dealer it went. They figured out it was loosing pressure, so they changed the fuel pump modual... change 3 times, as the pressure regulator is located within.
On the third time, prior to picking it up, I asked how long it had been sitting. It was a while, so I told the tech to go out and depress the bleed valve and let me know if there was pressure still in the lines,....NOPE!
So now they think I have faulty injectors. The take it apart, and low and behold, there's rust in my fuel lines. From where nobody knows. They removed the injecetors and all of they were not closing off all the way, as there were particles of rust wedging them open.
After getting a set of new injectors, the problem has not come back.
As to why the lines don't stay pressurized, the fuel leaks into the cylinders. The engine doesn't fire right away, because you have pooled gas in your cylinders, and not the atomized mix of gas/air. Once you are starting the engine, the fuel pump is engaged, and eventually the pressure will build up enough so that everything works.
Not sure that this is your exact problem, but it was mine.

I had a similar problem. Turns out the check valve at the pump was not working (this item fails often it seems) and pressure was bleeding back to the tank. The dealer finaly replaced the pump (check valve is part of the assembly) and I have not had the problem again.
The dealer first response was "this is common on our trucks and is normal" I refused to accept that and searched this site for similar problems and printed the reports I found and took them to the dealer (thanks fellow DAK owners). They could not deny the problem after that.

Hey, I have a 01 Dakota CC 4.7. I am having the same problem. Does this mean that the whole fuel pump needs to be replaced? I know its like $300 bucks...... Its got 41000 miles, having all the same problems as above. If it sits, it takes three + seconds to start, if you restart right away, its fine, and if it sits for about 20 min the problem is the same. I NEED HELP! anything will help! Thanks!

I have a 2001 5.9L that has a simular issue. Mine starts fine when cold, but after using the truck for a time (after it is all warmed up) it gets harder to start. I am not a fan of extended cranking and I have to actually give it a break some times. I find that if I just crank for a second the engine will barely start, but very poorly run (sputtering roughly, sometimes stall) for a few seconds then run fine. After it is running it runs great. This issue came up all of a sudden, and seems to be constant. I did replace the plugs with Autolights, the Cap and Rotor with brass replacements, and even the wires with 8MM pro type - with no real gains in the starting issue area. The truck has roughly 50K on it already, and all other areas of operation are fine, just this new hard staring issue. Any help out there. I plan on asking the dealer to investigate it the next oil change, but there is a lot of knowledge in this board and I am somewhat mechanically inclinded and prefer self help as it is usually cheaper.

Use 8 ounces of M.M.O in your gas for the next four fill ups. Then every other tankful.
It will clean your entire fuel-injection system. I think that some or all of your injector nozzles have corrupted spray patterns. It will fire under a full cold-run calibration, but then suffers after the PCM leans out the mixture....
M.M.O will properly clean them right out and bring them into spec.

I Know.......Question for ya!
Did your Dak run kinda crappy for a few minutes after a cold start before you replaced the injectors? Mine does the same kinda thing on morning cold starts, it starts right away and runs like a few clinders are sluggish to initiate a clean burn. (5.2 liter)
Might look into the injector replacement option to see if I can clear it up. Its been doing this for quite some time though. I also have very little pressure at my fuel rail after it sits for any lengthy period of time.
Did you truck run kinda crappy on cold starts too?
any info would be greatly appreciated.
