Engine runs good, fuel pressure is good, fuel quality is good. The Engine will shut down at 185F every time, only happens when engine is at idle. Does not show any warning lights before shut down and does not throw any codes to show that there is a problem. O2 sensor and mass air flow sensor are good. Throttle body plate is good. In shop at room temp.
