2013 Volkswagen Jetta Fuel System Diesel Power Train Engine Problems

I WAS DRIVING THE CAR APPROXIMATELY 40 MILES PER HOUR ON A STRAIGHT ROAD, WHEN ALL OF THE SUDDEN THE ENGINE LOST POWER AND I STARTED COASTING IN THE MIDDLE OF TRAFFIC. I WOULD PRESS THE GAS AND THE ENGINE WOULD REV, BUT NO POWER WOULD BE DELIVERED. IT WAS UNLIKE ANYTHING I'VE EXPERIENCED BEFORE WITH THE CAR. IT WAS LIKE I WAS IN A FALSE NEUTRAL, THE RPMS WOULD INCREASE BUT THE CAR WOULD NOT ACCELERATE WHEN I WAS PRESSING THE GAS PEDAL. SINCE THE CAR WOULD NOT REGAIN POWER, I WAS FORCED TO COAST TO A HALT IN TRAFFIC. WHEN I TRIED TO REMOVE MY KEY TO POWER DOWN THE CAR, IT WOULD NOT LET ME TAKE THE KEY OUT OF THE TRANSMISSION. IT WAS AS IF THE CAR THOUGHT THAT THE TRANSMISSION WAS NOT YET IN PARK EVEN THOUGH IT WAS. AFTER A FEW SECONDS I WAS ABLE TO REMOVE MY KEY, WHEN I TURNED THE CAR BACK ON, THE PROBLEM SEEMED TO GO AWAY. *TR
