I fixed found the problem that the dealership and skiiers choice couldn't find. The problem was with the transom remote. It was shorting out the whole system when it would get hot. I unplugged each of the remotes when the system was acting up and when i unplugged the transom remote it went from frozen to working perfectly. When i plugged the transom remote back in the system froze back up.. Skiiers and dealer said they checked remotes but they didn't.....
