I drive a 6mt 06 g35 coupe.

So I was sitting in the McDonald's parking lot and my car just stalled while in neutral. So I just started it back up and it was perfectly fine and I drove home. About 4 hours later I got back in it, when to start it, and it took longer than normal. When it finally did start, it made a loud, high pitched screeching noise. Sounded like a belt. And the vdc off, ses, and slip lights all came on. I drove it to work today, it runs fine. Just the lights on are and it takes an extra second or 2 to start. Any ideas?

Check all fluids before driving again and then troubleshoot

Possibly your camshaft position sensors and/or your crankshaft sensor are starting to go out. Take to an auto parts store and see if you have any codes pop up.

Check your brake fluid.

Go drifting. ¯\_(ツ)_/¯

I had this issue as well..I was sitting at a office max on idle and my car just shut off on its own...it was cranking but not turning over..after awhile I got it to start and tried to make it home without idling...I let it sit over nite to see if it was going to do it again and the same lights you say are on was on my dash to..I winded up changing the cam and crank sensors and haven't had an issue since... it's not hard just a bit of a tight spot to get bolts off..but hope if you didn't get it fixed yet that this helps

Check cam and crank sensors. Also check brake fluid and break pads. Its usally the brake fluid level. I had this same problem but mine was actually a sensor called a yaw sensor witch is in the door panal i think. Im not 100% sure but i think some guys take it out or turn it off when going to the track
