you might wanna take the edge off and see what it does. totally disconnect it from the truck. ive got an 03' and my truck would just shut off when i would be coming to a stop and in the message center it read batteries not charging. but then you could just start it right back up. tried reading codes on it come up with some funky codes no one could figure out. so i disconnected my edge and the problem was solved. they got a warranty on them to where you can send it back and get a new one. thats what i had to do. ive heard guys having different kinds of weird problems like that and ended up just being their edge box. so check that out.
