Car starts fine when it's cold. After driving for more than 20 miles, or starting and stopping more than four times, the car won't start. You sit for 30 minutes, then the car starts right up. Sometimes it'll start, then keep stalling. Brought it to three mechanics, no one can tell what the problem is unless they get it when it's not starting. By the time you have it towed there, it starts. They said possible fuel pump, possible module, possible anything. How am I suppose to fix this and stop getting stuck with it, if no one can figure out the problem?
