Took my 07 Z4M to the track today. In the middle of the second session the engine would completely shut off while under load. There weren't any dash lights on after this happened. I had to stop and restart the car and it appeared to be fine until it happened again.

Each time it happened in a turn following a hard braking zone. The car is stock with the exception of M track mode being coded in. This was in use when this happened. Outside of that, oil temp at 225, outside temp around 90 and just over 1/2 tank of gas.

Any thoughts?
