Well, my immediate answer of something to check is the TPS (Throttle Position Sensor) which is located on the driver's side of the throttle body. It has a plug going into it and it's held in place with 2 star key bolts. My second answer would be your battery terminals. My truck quit on me 3 times, and wouldn't start twice, and i realized that my positive battery terminal was almost shot. $0.97 at Wal-Mart solved that problem. As for the TPS, it's about $20-$30 at AutoZone. Of course, it could very well be something totally different.
