1989 Honda Prelude 4 cyl Front Wheel Drive Automatic 300000 miles

for some time I can leave home car will start ok. Pullin somewhere for a few minutes, go back to car and will not start, will turn over ok but will not start, leave it sit for 10 minutes or so go back and it will start. This can happen several times a week, but not all the time, like random

Next time it happens don't wait for nothing, do below immediately to determine whether it's a fuel or spark problem: Cranks but no start condition: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

All of the obvious tests have been carried out including spark plugs, fuel pump has been checked and qualified mechanics say they cannot find the fault. Ignition is working fine.
