I-pilot V2 problem

I went out to try my new I-pilot yesterday and had problems with it.
I set the spot lock and it started holding the spot.
The boat started drifting and I looked at the remote, the spot lock was off.
I turned it back on and the boat started to move. The prop shut off and after a few seconds the spot lock turned off also.
The next try did the same thing, I hit the left button and the motor turned with no problems. I tried the auto pilot and the same thing happens, prop stops and the motor turns to keep course.
Does anyone know what might cause this?
I checked the connections and they seem fine.

Only thing i can think of is if you touch any function while spot lock is on, it disengages. On a terrova, even if you touch anything on the foot control it happens.

none of the buttons were pushed. its like the power was shut off but the buttons worked for turning it.
