1999 Cadillac Sts

VEHICLE SHUTS DOWN AT CRUISING SPEEDS, LOW SPEEDS, AND IDLING. ALL SYSTEMS SHUT DOWN WITHOUT WARNING. VEHICLE MAY OR MAY NOT START BACK UP IMMEDIATELY. I HAVE SEEN SEVERAL OTHER COMPLAINTS ON SAME ISSUE BOTH ON NHTSA AND OTHER CHAT BOARDS. THIS CAUSES A HAZARDOUS DRIVING CONDITION FOR MYSELF AND OTHER DRIVERS. CAN BE ESPECIALLY DANGEROUS ON HILLY AND CURVED ROADS BECAUSE ALL POWERED STEERING AND BRAKING SHUTS DOWN AS WELL. *JB
