Truck starts and runs good, but when driving, it shuts off. It restarts easily and drives for a bit then shuts off again. Any ideas?

Yes, I have seen these trucks have a problem with the ignition module (TFI) and the EEC relay. Here are the locations of each so you can change them out 9 times out of 10, it will fix the problem. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
