2010 BMW 535XI Engine Problems

TWO TIMES IN THE PAST FIVE DAYS MY 2010 BMW 535XI HAS SHUT DOWN. EACH TIME IT HAS MALFUNCTIONED(12/24/16 AND 12/29/16), THE AUTOMATIC DOWNSHIFT ACTIVATED). ONCE WHILE TRAVELING UP A HILL AT APPROXIMATELY 35 MILES PER HOUR AND ONCE WHILE TRAVELING IN EXCESS OF 55 MILES PER HOUR ON A VERY BUSY HIGHWAY. I WAS NOT ABLE TO RESTART THE VEHICLE AND HAD THE VEHICLE TOLLED TO A LOCAL GARAGE. SHORTLY AFTER ARRIVING THE TOW OPERATOR STARTED THE VEHICLE. IT STARTED WITHOUT HESITATION A SECOND TIME. I LEFT THE VEHICLE AT THE REPAIR SHOP AND PICKED IT UP FOUR DAYS LATER. IT HAS STARTED AND OPERATED AS BEFORE UNTIL DAY FIVE WHEN I WAS TRAVELING UPHILL AND IT INITIATED A DOWNSHIFT AND STOPPED OPERATING. EACH TIME THE FUEL PUMP FAILURE INDICATOR CAME ON. IT IS A SCARY FEELING, ESPECIALLY SINCE EACH TIME I WAS IN THE MIDST OF OTHER VEHICLES....
