Hopefully it's something as simple as a battery or an alternator. Just changed both of mine last month.

if the alternator crapped out you would of had a battery light pop on. Did you notice anything like that? Also when your alternator dies, Your truck is running only on battery power and since there is not power coming from the alternator, when its depleted, it be like having a dead battery, no or hardly any power at all. If you have enough to crank i doubt its an alternator

for ***** n giggles you can stick some brake clean with a straw into your TB and give it a few shots. Starts up or tries to, its definatly a pump
