We have replace 4 crank trigger sensors on our 2001 F350 Super Duty since we got it. Yesterday I was driving the truck at 70 miles an hour on the freeway when it started to shake. I thought I had a flat so I lifted and got over to pull off the freeway, but the truck kept shaking and the speed was dropping fast. I turned on the emergency flashers and could do nothing except try to get it off the freeway. It stalled so I pulled off. It would not restart. After about 20 minutes in 16 degree temperatures I tried to restart. It did restart and I got up a ramp but the truck was chugging all the way and would not go above 15 miles per hour. This truck has quit in the worst places with no warning that the crank trigger sensor was going out. This is not the first time I have been not only stranded but in a dangerous place. This truck has not been abused and has had maintenance done regularly. Ford and international harvester (maker of the part that dies) says that they have not heard of any others like this. But we have a lot of friends who drive the same truck and just about all of them have had this problem. We all carry spare crank trigger sensors and 10 mm sockets and drives to fix the problem when it happens. It is really an issue when you have to carry spare parts with you because you never know when it will go out. The part was in the truck less than 200 miles when it went. We replace the same part during christmas and we don't drive the truck every day.
