Nouthing
Replace the fuel pump. You have a fuel return line. This adds heat to the fuel tank. When the pump gets to a certain temperature, it shuts down. Adding cold fuel retracts the pump and it works again.
Check crankshaft sensor.

sounds like it could be plugged injectors or a timing problem.

Check your ECM fuse. There should be 2 fuses for your ECM. It's the ECM that controls the function of the fuel pump. Good luck friend and it's also common for the wire harness from the frame to the fuel pump to go bad due to corrosion from the bad weather we get in the winter and rainy spring and fall.

Does the truck have a push button selector on the dash? If so, you need to replace the drive motor on the transfur case.
