Engine runs good, fuel pressure is good, fuel quality is good. Once engine is at 185F the engine will shut down. Does not show any warning lights before shut down and no codes pop up that there is any problem. O2 sensor and mass air flow sensor are good. Throttle body plate is clear and good. This problem only happpens at 185F and is at idle, does not happen when engine is revd.
