HELP! Truck cuts off after driving!!

Since it started getting cold at night if I don't plug in my truck or let it warm up to operating temp in the mornings it will cut off riding down to the road. When it did this I just coasted over and pulled off the road, my chip was in stock setting, I tried crank it back up and it just spins then finally cranks but runs really bad, like it has a HUGE cam in it then eventually it evens out and the truck is fine. But every time now I let it warm up and its fine. Also if I try to crank it cold it seems a little slow to start. I think it might be the glow plugs and that the engine isn't getting properly warmed when I start it cold. The dealer said that it might be some kind of exhaust pressure valve. What do ya'll think.

I checked the relay and it has voltage, how do I check the glow plugs themselves?

Your oil is low. Had the same problem. Truck wouldn't run when cold. I resorted to letting it run while I was getting ready for work. Then, I changed my oil and haven't had a problem since. It was even doing it when it was warm outside. I would check the oil levels in the pan as well as in the HPOP (or where ever Marc said to check it in another post).

I think you guys are right, I had gone like 20,000 miles on the last oil change without checking it and I just changed it the other day, I'm gonna leave it unplugged and crank it cold tomorrow and see if my problem is gone.

20k without checking/changing, you a brave man.
Oil maintenance is the cheapest/easiest way to ensure long engine life. I had to learn this one the hard way , I hope you dont have to.
My lesson was on an old Rabbit diesel, got it with like 5k miles on that oil change and it was 1qt low when I went to change it. So I decided, I'll just change it next time at 3k, and wont have to worry about it. At ~1500 miles, it started starting hard, then got noisy. I checked the oil, 3.5 qts low and it only held 4. Bad news. Adding oil too late to help then. Engine very noisy, went no where and threw rod out the side.
The good news was I had like $60 in that car, so it was a relatively cheap lesson. The PSD seems to hold a better resale than the old rabbits, replacement=$$$$.
Check it often and Change it regularly.
I'll step down from here now, and put my soapbox away.

They are right 20k on an oil change is way to much. A PSD abuses the engine oil worse than any other engine out there. It uses the engine oil basically like hydraulic oil. Pressures from 450 psi to 2400 psi+ to fire the injectors. Change your oil regurally!!! I know quite a few peolpe that have replaced cps do to low oil.
