Hello, over the past 2 weeks when I drive my warning lights come on and then the truck shuts off but yet my music still works/ my ac still runs and I have to pull over and restart the key. It was very sporadic. I replaced the battery b/c it tested bad. I drove it 2 days ago alot and never shut off, then yesterday on my way out it would not stay on and 5 miles away from home after shutting off 5-6 times I had to get towed home b/c it would not start. The engine turns over like its going to start but never does. Any idea what could be wrong? I am thinking fuel pump, auto shops charge $100 just to get it hooked up to a 'scanner'. Thanks!

You need to check for spark and gas, also compression. Check this video out for doing that. One is missing!
Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
