2005 MAZDA MPV Engine And Engine Coolingengine Problems

TL* THE CONTACT OWNS A 2005 MAZDA MPV. THE CONTACT STATED WHEN TRAVELING AT 15-35 MPH, THE VEHICLE WOULD STALL WITHOUT WARNING. IN ADDITION, THERE WAS AN ABNORMAL KNOCKING SOUND COMING FROM THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER FOUR TIMES WHERE THE ENGINE COIL WAS REPLACED EACH TIME. THE FAILURE PERSISTED. THE FAILURE MILEAGE WAS 35,000 AND THE CURRENT MILEAGE WAS 74,000.

WAS EXITING PARKWAY WEST WESTBOUND EXIT FOR ROUTE 22 IN PITTSBURGH FOR WEIRTON, WV; ENGINE SHUT OFF ON ITS OWN WHEN ENGINE WENT OUT OF OVERDRIVE AND INCREASED ITS RPMS AND I LET OFF OF GAS PEDAL TO BRAKE - LOST POWER STEERING AND BRAKES, MAINTAINED CONTROL, SHIFTED TO NEUTRAL, RESTARTED ENGINE - TRACTION CONTROL LIGHT REMAINED ON FOR REST OF TRIP TO WV UNTIL KEY WAS RETURNED TO COMPLETELY "OFF". THEN ALL LIGHTS WERE RESET TO NORMAL - NO CHECK ENGINE WARNINGS. THIS HAS OCCURRED ABOUT 5 OR 6 TIMES AGAIN, ALWAYS AFTER ACCELERATING, AND THEN LETTING OFF THE GAS PEDAL. I HAVE BEEN ABLE TO REPLICATE WITH VEHICLE IN PARK - JUST REV ENGINE TO AROUND 2500 TO 3000 RPM, AND LET OFF THE GAS - IT SHUTS OFF EVERY TIME ON ITS OWN. SO FAR I HAVE NOT BEEN REAR ENDED, BUT? *TR
