If it won't restart upon shutdown don't wait do below immediately to determine if its fuel or spark problem.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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 with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing-Depends on what type ignition system is yours,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, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and keep testing
