Car shuts off when idling in park, and won’t start. If I wait 5 min it starts up perfectly.

there are numerous reasons your vehicle may be shutting off at idle. I strongly recommend taking your vehicle to a qualified mechanic certified with repair pal for proper diagnosis. the condition which you describe as occurring will probably require onboard computer diagnostics. hope this provides you assistance.

*Hands-on* testing will be required while this concern is present - be prepared to leave vehicle at auto repair facility until testing can be successfully completed. Good luck!
