1987 crown Victoria, when it get hot it will not start. The starter turns it over, but just won't start until you cool it down.

replace the black modgel under dis cap,or the timeing chain ,gears are worn out.out of time.it may just be timed to high.have timeing checked.

Ignition module defective. Fuel pump relay melting and distorting connector. Next time it stops, have someone cycle key while listening with fuel cap off. check for spark while someone turns key. Rarely is it the ECM but, it's possible.
