Turns out there was a short in the wiring. The reason it would stop going up at 5 or 6 feet is because the wire that came down from the platform would bend out of place, disconnecting the wire. I had to cut the wire and splice it back together. Once I did that our ip problems were resolved. We still seem to have forward issues though. We can still get it to work it just sometimes requires multiple attempts to get it started moving forward.
