Car wont start sometimes but other times it will. When it doesn't it has no spark coming to the spark plugs. Then when it does start it will idle for about 5 mins. Then shut off. What would cause it to do that?

Sounds like an ignition switch problem-Do below

Next time it refuses to start don't wait for it to make up its mind-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, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

Yeah there's no fuel problem. When it doesn't want to start there is no spark from the plugs. Then other times it will start and idle for a few mins. Then it will just shut off and maybe wont start again.
