The truck had a wiring issue where it wasn't firing on all cylinders, I continued to drive it till it just wouldn't start anymore. Although it sounded like it wanted to so I took fuse box apart got it to fire on all cylinders and to finally start but only run for a ½ a mile then shut off will only run really bad if I pump gas really fast it has black buildup in intake.
Do you
have the same problem?

It sounds like the fuel pump is going out, but can you run the codes to see if any are stored?

Here is a guide to help:

Also, when the engine stalls, can you turn the key on without cranking the engine over can you hear the fuel pump run in the tank for about 5 seconds?
