ON MAY 26, 2006, MY MERCEDES BENZ 1999 300D LOST ALL POWER DURING ROUTINE OPERATION. THE CAR STALLED WHILE IN MOTION IN REGULAR TRAFFIC, AND WAS REQUIRED TO BE TOWED TO A MERCEDES BENZ DEALERSHIP. I WAS NOTIFIED THAT THE REASON FOR THE FAILURE WAS A DEFECTIVE CRANKSHAFT POSITION SENSOR. PART NUMBER 003-153-74-28. THE PART WAS REPLACED. WHEN THE CAR WAS RETURNED, IT WAS DRIVEN NO MORE THAN 12 MILES WHEN THE EXACT SAME CONDITION RE-OCCURRED WHILE THE CAR WAS IN MOTION IN TRAFFIC. THE CAR WAS TOWED AGAIN AND REPAIRED ON JUNE 2, 2006 AT A MERCEDES BENZ DEALERSHIP, AND THIS TIME THE REASON GIVEN FOR THE FAILURE WAS A BROKEN PRE-FILTER AND MAIN FUEL FILTER. PARTS NUMBER 601-092-01-05, 601-090-16-52, AND 601 997-01-48. PLEASE INVESTIGATE THIS MATTER PROMPTLY, AS THERE APPEARS TO BE A CONDITION WHICH CAN CAUSE THE LOSS OF ALL POWER WHILE THE CAR IS IN MOTION. *NM
