Driving 30mph car begins to surge and slow down had to pull over to road shoulder. Fuel gauge shows empty when there is a full tank. Cut the engine off for five minutes, start engine tried to drive the car is still surging and slowing down, then starts to run normally. This is the second occurrence the first occurred in March 0f 2013.
While entering interstate highway, engine balked like bad gas. After two or three tankfuls and the vehicle dying in traffic, I left it with my dealer to find the problem. After a week, the vehicle had not died for them so I brought it home, only to continue with the same dying and hesitating when accelerated. A month or so later the dealer kept it again for about 5 days and it still did okay for them. They have no idea what the "problem" is. We have parked the car in our garage because several times we have narrowly escaped being rear-ended, when turning corners, crossing railroad tracks, etc. I contacted Ford motor CO. In michigan and they do not "have this problem with other vehicles" and don't seem to know what I'm talking about. Mechanics in two other garages have driven the vehicle and have not located the problem. Help!!.
