The cutting out intermittently sounds like it could be a CPS, too.

Yeah Pop, thought of that but the added throttle didn't make sense for a CPS

Mine did exactly the same when my IPR went out with the exception that I could get it running enough to drive home, but it ran like crap. I did have to hold the pedal on the floor to make it crank.

Injection Pressure Regulator. Basicly controls the high pressure oil pump from signals from the PCM.

Here's a link with some pictures in it.

If you're up for it here are some instructions on removal and cleaning. http://www.dfuser.com/Install%20Guid...0Regulator.pdf
I didn't have any luck with cleaning it, but many have. Bob (Guzzel) sells them or did and is very reasonable and very fast service. PM him here or contact him through diesel orings.com. Link in my signature.

I was able to crank the truck and drive it few miles. It seems like it gets better if I let it sit for a while. Does this mean anything?

How did you crank it? How did it run? How did it die?

I had to jump it off and have the throttle to the floor. It ran good for about 1 minute then started dying. Then it died even while revving it up to about 3000rpm

Sounds like the IPR or at least that's the way mine did. Try cleaning it if you want, or get the codes read if you want to be sure. I looked at Bob's site and he is out of IPR's at the moment.

I pulled the thing to autozone to get the codes read ad the truck
wouldn't start again so the codes wouldn't show up. Very frustrating.

Most AutoZone reader won't read PSD codes anyway.
