Fuel Pump problems of the 2011 Ford Fusion

Vehicle started to have problems around 83,000 miles. My daughter would just be driving along and suddenly the car would just stop accelerating and go to idle. She would have to coast to the side of the road to get out of traffic. She was able to turn the car off and start it again and clear the problem. It would go a couple of weeks without incident until all of the sudden would happen again. On most occasions, the yellow "wrench" light would come on as well. We first assumed it was bad gas or the fuel pump, but after researching discovered a lot of complaints with the exact symptoms that pointed to a faulty throttle body. I decided to submit a complaint after last night her car once again stopped accelerating on a bridge with a police officer behind her whom proceeded to pull her over. Fortunately, the officer was understanding to the situation. It is very unsettling to have your inexperienced 17 year daughter on the highway with a vehicle that operates in this capacity. Ford has been manufacturing cars for how many years and this is still the best they can do? to be driving down the highway at 60 mph and your car just transfer to idle speed. Ridiculous!.
