2003 E500 V8:WHEN THE ENGINE IS COLD WE DRIVE UP TO TWO TO THREE LIGHTS, THEN WHEN @ IDLE IN GEAR @ THE LIGHT STOPPED, THE ENGINE JUST SHUTS OFF, W/O CHECK ENGINE LIGHT. PLACE BACK INTO PARK, CYCLE KEY & THE ENGINE WILL START UP JUST FINE & WILL NOT DO IT AGAIN TELL YOU LET IT SIT & GET COLD. THIS HAS HAPPENED 6 TIME IN THE LAST TWO MO'S.
