Having the same problem on my 2007 Edge. Bought it in 2007 and now wrench light comes on, speedometer stops etc. It does it with my wife so I drove the car a week and nothing happened, my wife gets back in it and a mile down the road it starts doing the same thing. I ordered a TPS sensor and put it on. Car ran great for me but my wife drives it and it does it again. I told her to turn off her iPhone 5c, car runs fine. Tested this theory for a month every time she turn her iphone5c on the car stalls. May seem far fetched but it's her iphone5c somehow interfering with the system
