I was traveling approximately 55 mph under normal driving conditions when the car lost power and I was able to drift to side of road. Wrench light came on. I waited a few minutes and restarted the car. It idled rough at first but I was able to continue the drive home without incident. I researched this problem on the internet and discovered that Ford fusions of my year and mileage were experiencing this issue. The first recommended coarse of action was to use a throttle body cleaner. I did this and the car seemed to operate fine under conditions 25 mph. I set off to work on the 6th and the car shut off on me six times before I could make it twenty miles and get back to the house. This is an obvious manufacturers defect and needs to be handled appropriately.
