I HAVE A 1988 F-150 WITH A 302 WITH FUEL INJ.LIVE IN MICH. AND WHEN THE TEMP COMES UP ON THE TRUCK THE ENGINE WILL NOT START WHEN WARM.THE TRUCK HAS ALSO EVEN SHUT DOWN WHEN DRIVING.YOU WAIT ABOUT AN HOUR AND IT WILL START RIGHT UP.IT SEEMS TO RUN LONGER WHEN THE OUTSIDE TEMP IS COLDER THAN WHEN IT IS WARM.ARE THERE TEMP SAFTEY SWITCHES ON THESE TRUCKS? OR IS IT COMP. RELATED.OTHER THAN THAT THE TRUCK SEEMS TO RUN FINE....FOR AWHILE....IT IS A 4X4 WITH 100,000 MILES P.S. IF IT IS REAL COLD OUTSIDE IT SEEMS TO TAKE A LONG TIME TILL IT ACTS UP...

I would suspect the ignition module on the side of the distributer. You can try one from a junk yard for about $10 around here. Do you know if it is missing spark or fuel when it quits? Could also be a fuel pump or fuel related.
