display freezing up

[banks]

has any one had this problem or heard of it, i was in tow mode pulling my camper down the road and looked up at the display and it was froze. i pulled over and reprogramed, it stared working again but later down the road done it again. stopped again deprogramed it and unplugged it to check the u port connection. reprogramed it and started working but froze up again. when i made it home and unhooked the camper, i but it back it performance mode and haven't had it happen since...?
