My '86 Tempo cuts out when running. I could be at highway speeds and it quits. If I wait a minute or two it will start right up. It also will cut out at a traffic light or when running at low speed as well. As long as I give it a minute or two before trying to start the engine it will start right up and run down the road a few minutes then quit. I'm wondering if it is an ignition or fuel problem. The car was taken to a mechanic who had the car for about a week and he stated the car gave him no troubles. He supposedly checked it out and could find nothing wrong. I hope someone has an answer to my problem.
