AT NIGHT, WHILE AT SPEED (60 MPH) IN CENTER LANE OF A CROWDED HIGHWAY DURING EVENING COMMUTE, THE ENGINE STOPPED, RESULTING IN LOSS OF PROPULSION, POWER STEERING, AND POWER BRAKES. FORTUNATELY WAS ABLE TO COAST TO A STOP ON THE RIGHT SHOULDER WITHOUT COLLISION. WAS ABLE TO RESTART ENGINE NORMALLY AND PROCEED HOME (ABOUT AN HOUR) WITHOUT FURTHER INCIDENT. NEXT DAY DID SOME LOW SPEED (5 MPH) TESTING IN A QUIET AREA TO INVESTIGATE POSSIBLE CAUSES. COULD NOT REPLICATE WITH ANY BUTTON ON REMOTE OR STEERING WHEEL. SYMPTOMS COULD BE REPLICATED BY PRESSING ENGINE START/STOP BUTTON WHILE IN MOTION. THIS BUTTON IS TOO HIGH TO HIT WITH DRIVER'S KNEE AND LOCATED WHERE ACCIDENTAL TOUCH BY DRIVER'S ARM/HAND IS HIGHLY UNLIKELY. BOTH DRIVER AND FRONT SEAT PASSENGER SAY THIS BUTTON WAS NOT ACTIVATED DURING THE INCIDENT. NO FURTHER RECURRENCE IN NORMAL DRIVING ON THE FOLLOWING DAY. NO SYSTEM MESSAGES ON VEHICLE INFORMATION DISPLAY. PLAN TO TAKE TO DEALER NEXT WEEK FOR FURTHER INVESTIGATION. MILEAGE 55100
