I had a similar problem with my 89 Ranger back a few years ago. It would start and run fine when cold but if you drove a few miles and shut it off it would refuse to start again. At first it was intermittent but I had to get towed once or twice when it refused to start at all.

It turned out to be a bad coil. The resistance would go way up when it was hot. I finally was able to figure it out when it stopped working altogether.

If I were you, I would carry around an ohmmeter so that the next time it happens, you can test the resistance of the coil. Compare against what the resistance should be.


Good luck
