After car runs for more than 30 minutes car will not start unless we lift the hood and let engine cool off then it will start. We were told fuel pump or engine module. We did change water pump, thermostat?

The only way to catch this problem don't wait check for fuel and spark -do below to determine which one.

Get a helper 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, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
