2007 BMW 328 Engine Problems

THE ENGINE COMPLETELY SHUTS DOWN AT HIGHWAY SPEEDS WHEN BRAKING OR ACCELERATING MODERATELY HARD, WHICH IN TURN SHUTS DOWN POWER STEERING AND PROBABLY THE POWER BRAKES!!! THIS HAS HAPPENED FOUR TIMES. FOR EACH OF THESE EVENTS, I WAS DRIVING THE CAR NORMALLY AT HIGHWAY SPEEDS FOR AN EXTENDED TIME, PROBABLY LONGER THAN TWO HOURS. IN ONE INCIDENT ON APRIL 12, 2017, THE ENGINE SHUT DOWN WHEN I QUICKLY ACCELERATED TO ALLOW FOR SAFE TRAFFIC FLOW INVOLVING A TRACTOR TRAILER. ANOTHER INCIDENT ON SAME DAY INVOLVED MODERATELY HARD BRAKING AS I APPROACHED STALLED TRAFFIC ON THE TAPPAN ZEE BRIDGE. I WAS IN THE LEFT LANE AND THE ROAD DID NOT HAVE A SHOULDER. THIS CREATED A SERIOUS HAZARD WITH HEAVY TRAFFIC. A THIRD INCIDENT ON THE SAME DAY OCCURRED DURING MODERATELY HARD BRAKING AS I APPROACHED A TOLL BOOTH. LOSS OF POWER STEERING (AND PROBABLY POWER BRAKES) CREATED A SERIOUS HAZARD....
