2011 FORD F-350 Engine And Engine Cooling Problems

MY WIFE AND I WENT TO PICK UP THE 5TH WHEEL CAMPER FROM THE STORAGE AREA. I BACKED UP TO THE CAMPER, PUT THE TRUCK IN PARK AND DID A FEW THINGS BEFORE MY WIFE GOT OUT. AS SHE WAS GETTING OUT I MASHED THE BRAKE PEDAL FAIRLY HARD AND PLACED THE TRANSMISSION IN REVERSE. I DIDN'T WANT THE TRUCK MOVING WITH THE PASSENGER FRONT DOOR OPEN AND WHACKING MY WOMAN. AS THE WIFE WAS GETTING READY TO SHUT THE DOOR THE ENGINE RPM WENT SKY HIGH ON ITS OWN. MY WIFE LOOKED AT ME AS IF TO SAY WHAT THE HECK ARE YOU DOING! I GAVE HER A BLANK/SCARED LOOK AS IT WAS NOTHING I DID TO MAKE THIS HAPPEN. I GLANCED AT THE TACH AND I WAS UP OVER 2500 RPM, IN REVERSE, BUT THE TRUCK WASN'T TRYING TO GO ANYWHERE. IT WAS AS IF IT HAD DISENGAGED...

HAVING OWNED THE TRUCK LESS THAN A MONTH AND DRIVING IN CITY TRAFFIC, THE VEHICLE LOST POWER AND WENT TO IDLE. THIS HAPPENS REPEATEDLY. SEEMS TO OCCUR PRIMARILY IN CITY DRIVING - NOT HIGHWAY DRIVING. HAVE BEEN TO THE DEALERSHIP SEVERAL TIMES WITH NO SOLUTION. THEY CAN FIND NO CODES. THIS IS DANGEROUS AS I COULD BE MAKING A LEFT TURN IN HEAVY TRAFFIC WHEN IT DROPS TO IDLE AND COULD BE INVOLVED IN A SERIOUS ACCIDENT. WE HAVE NOW OWNED THIS TRUCK FOR A YEAR AND IT ONLY HAS 6,800 MILES ON IT DUE TO THE DANGER OF DRIVING IN TRAFFIC. MOST OF THESE MILES HAVE BEEN FROM REPEATED TRIPS TO THE DEALERSHIP TO NO AVAIL. *TR

THE VEHICLE WILL SUDDENLY AND RANDOMLY LOSE POWER. IT MAY LAST A FEW SECONDS TO SEVERAL MILES. EVENTUALLY THE POWER COMES BACK AND THE VEHICLE CONTINUES MOVING. THIS HAS HAPPENED AT 55 MILES PER HOUR WHILE HAULING A FULL TRAILER. IT HAS ALSO HAPPENED IN HIGH TRAFFIC AREAS WHICH PRESENTS A DANGER TO THE VEHICLES FOLLOWING ME. I HAVE HAD THE VEHICLE IN TO A FORD SERVICE DEPARTMENT SEVERAL TIMES AND THEY CAN'T DETERMINE THE PROBLEM. THE LOSS OF POWER HAPPENS SEVERAL TIMES EVERY WEEK. AT THIS TIME FORD IS REFUSING TO ADDRESS THE PROBLEM. *TR
