2017 LINCOLN MKX Electronic Stability Control Esc Problems

WHILE DRIVING AT NORMAL HIGHWAY SPEED'S THE ENGINE SHUTS DOWN WITH NO THROTTLE RESPONSE OR ACCELERATION. THE ONLY OPTION IS TO COAST THE VEHICLE TO THE SIDE OF THE ROAD. AT THAT POINT THE ENGINE IS AT A VERY SLOW AND ROUGH IDLE WITH THE ORANGE SERVICE WRENCH AND WARNING LIGHTS ILLUMINATED ACROSS THE DASH. TO REGAIN A THROTTLE RESPONSE, THE OPERATOR MUST TURN THE VEHICLE OFF AND RESTART IT, THIS RESETS SOMETHING FOR A SHORT PERIOD OF TIME. THIS IS THE FIFTH TIME THAT THE VEHICLE HAS SHUT DOWN DURING NORMAL TRAVEL AND IT HAS BEEN TO THE DEALER WITH NO CODES FOUND AND NO SOLUTION. I NOW CONSIDER THIS VEHICLE TO BE VERY UNSAFE AFTER HAVING THIS FAILURE WHILE BEING IN THE LEFT LANE PASSING A TRACTOR TRAILER TRUCK.
