I have a truck that will start right up when its cold, but when the engine warms up it will either die or not start. When it was taken to the mechanic it would start up for them and they couldnt find anything wrong with it. I have seen some other people having the same issue but have not got any response back. Any idea or response will be much appreciated.

 

your engine will have a much harder time starting when it is hot than when it is cold because when it heats up everything "swells" and becomes a tighter fit ya know? as for it just dieing i have no idea.

 

Sounds like fuel problem. How long does it take for the vehicle to quit? If it does stay running how long does it have to sit before it will start?
