Thanks for the responses.

Julyer - I haven't changed the IPR, but everything checked out on the Snapon scanner.

Jim - I have already covered the basics. Truck was running like a new one and just died while driving 55mph, so things like bad batteries, fuel, compression, etc really don't apply. When we scanned, high pressure oil was in range while cranking, but didn't start.

For some reason, something is not letting the injectors fire, like they are not getting 110V, but the buzz test was fine. Since I can get it to run, with help from starting fluid, I'm guessing the IPR, ICP, or some other sensor must be failing. I plan to change them this weekend. Like I say, I can get it to run, it sounds fine when running, but always dies after a few minutes.

Any other items I should check?

Thanks
