Gotcha. I've never had an issue with the power port. Blew the fuse once, but that was it.other then the common grounds not sure really. my hptuners also got cut off when we tried to read your pcm. maybe try moving the wires to the obd port while plugged in see if you can make it disconnect. the power port is also on the same fuse as the obd port, so if the power port also goes dark it could be a fuse box issue.
