I have a 1987 Ford E-150 5.8L 4bbl that stalls.
It always starts when it is cold, and drives just fine - EXCEPT on hot days it will stall after about 15 minutes driving - but only when it is idling at a traffic light. Once it stalls, it will not restart for at least 20 minutes. However, once it cools down it will start right up like nothing happened.
I suspect vapor lock, but the last time it happened it was 65°F - where before it had to be in the 90's! I am hoping this was just a fluke, but I am extremely reluctant to drive it because it always stalled AT a trafic light and the dang thing is hard to push off the the side of the road - I mean it weighs over 5K!
I'm looking for both help in diagnosing the problem and possible solutions.
