This has been happening the last couple weeks. Not during a cold start after sitting overnight. I'll go to the store etc and after the car sits for 30 min to 2 hours I start it and it loses power and turns off. Today it took 3 times for it to remain running. Either that or I have to immediately give it gas to prevent it from shutting down.

My code reader says everything is ok. I'm due for an oil change so I guess I'll add this to the list.

2012 G37x with 59K miles.

Anybody have the same experience?

Might also want to clean the throttle bodies.

I cleaned the MAF sensors. I also noticed my air filters were a little dirty. I last replaced them in February. 15k miles ago. I'll be replacing them.

A weak fuel pump would leave no codes via obd2 scanner. Should have the fuel pressure checked

Thanks for the suggestion. So far it's running fine after cleaning the sensor and changing the filters.
