Hi and welcome to the forum

Does the battery light on the dash come on when you turn the key on and then go off when the engine starts?

The truck died when you were driving? That puts it on the alternator right there. You can remove the battery from a car when the engine is running, and it will continue to run. If it died, you aren't getting spark because the alternator isn't providing enough power.
