THIS PROBLEM HAPPEN THREE TIMES IN ABOUT 6 MINUTES IN ONE NIGHT. WHILE DRIVING AT 70 MILES PER HOUR. THE ENGINE CUT OFF, ALMOST BEFORE I KNEW WHAT HAPPEN THE ENGINE STARTED BACK RUNNING. IN LESS THAN A MINUTE IT HAPPEN AGAIN. THE ENGINE CUT OUT THEN STARTED BEFORE I COULD DO ANYTHING. THE THIRD TIME IT CUT OUT COMPLETE AND STAYED OFF. I WAS ABLE TO MOVE THE SIDE OF THE ROAD AND STOP AND RESTART THE CAR. IT WAS VERY SCARY, ALL THE LIGHTS WERE OFF AND I WAS ON A BUSY HIGHWAY AT NIGHT. IT'S HAPPEN BEFORE ABOUT A YEAR AGO. I MENTION IT TO THE DEALER, THEY ACTED AS IF IT WAS NOTHING THEY WERE AWARE OF. *TR
