SOMETIMES THIS CAR WILL CRANK OVER BUT NOT START, IT SEEMS TO DO IT AFTER YOU DRIVE FOR 10MINUTES OR LONGER, PARK THEN TRY TO START BUT JUST TURNS OVER NO CHECK ENGINE LIGHT

Cranks but no start condition-do below to determine whether it's fuel or spark issue:

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.
