This sounds like the classic IPR solenoid issue. The IPR solenoid is an electromagnet. When electromagnets start to fail, they become temperature sensitive. They will work when they are cold and then lose their grip when warm. So, with respect to this engine, the IRP sets the injection pressure for the injectors. When the IPR solenoid drops out, the pressure goes to zero and the truck dies. Will not re-start. Once the solenoid cools off, it starts right up like nothing was ever wrong until the solenoid heats up again.
You can swap the solenoid by itself without having to pull the IPR. Just take the pigtail loose, remove the tin nut, and slide the solenoid off and slide the test solenoid on. I keep a spare in my glove box just for this purpose.

I wonder if clouds ever look down on us and say, "Hey, look - that one is shaped like an idiot!"
