VEHICLE SHUTS DOWN WITHOUT NOTICE, QUITS IN TRAFFIC, ON THE HIGHWAY AND ONCE WHILE TURNING ACROSS TRAFFIC. AFTER VEHICLE SETS FOR ABOUT 45 MIN IT WILL START AGAIN. HAD VEHICLE TOWED TO A SHOP AND THEY REPLACED A COMPONENT THEY SAID WAS BAD, 600.00 AND FOUR DAYS LATER WE PICKED UP VEHICLE AND TO A TRIP TO THE MOUNTAINS WHERE IT QUIT AGAIN AND LEFT US STRANDED IN THE BACK COUNTRY OF COLORADO. AFTER ABOUT A HOUR OR SO IT STARTED AND WE TOOK IT BACK TO THE SHOP THAT DONE THE WORK AND THEY HAVE HAD IT FOR OVER A WEEK AND HAVE NOT SOLVED THE PROBLEM. *JB
