My 92 Isuzu Rodeo has been acting up for the past month. Lately when I drive for a while and the engine warms up it wont start again until it cools down. It starts just fine going short distances. I replaced the starter and had the battery and alternator checked. All is working fine. Any ideas?

Next time it refuses to start don't wait do below to determine if its fuel or spark problem

Get a starting fluid or ether and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -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, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
