Wait like your truck just dies randomly? If so that almost sounds like a fuel pressure problem. I have a few tests for that.
1. Make sure fuel pump runs
2. Remove quick disconnect from fuel filter, let fuel drain out, reconnect the line, and turn key to ignition(turning fuel pump on). Then check that line again, fuel should come out. Also check your Fuel Pressure Regulator located near cylinder 1, opposite of plug. Remove the little line(be careful they are hard plastic lines!) When you try to start no fuel should come out. (Fuel coming out means FPR is broken)
Try to hit back with some more info ill try to help u out. I got a 97 sonoma with a hell of a lot of problems. My post is 97 sonoma. :P
Oh and the cutting out, does that only happen in neutral? Or while you are still in gear? Mine cuts out in neutral for about the first 1-5mins UNTIL it is warm im gonna replace my IAC sensore see if that helps me any.
