Edge has had this problem for a long time. I was reading on another forum and someone called and talked to edge and they said that their electronics in the boxes weren't automotive grade. Either way, there is a problem there and all it takes is someone to file a lawsuit because their truck shut off and they got into an accident. I think it has something to do with the heat under the hood cooking the electronics in the box. Replacing the sensor probably won't fix your problem. If you had a different programmer then you could test their theory.
