Sounds like possibly a posse battery terminal.

We have a 2007 Tahoe Q7i and just had this problem tonight. Were you able to fix yours, and if so, what was the problem? We were out in pretty choppy water, so we were thinking that maybe a connection came loose, but couldn't find anything. Hope you can help!

There is a 15v fuse behind the motor...in a little black box straight back from the red reset button. Kind of hidden. It was blown. Easy fix. However it keeps popping anytime we put in reverse and if we dont put in neutral easy it will blow. It is a problem in the gear shifter...we havent taken it apart yet to see but must be pulling a wit of some sort. We had the complete boat taken apart and no issues anywhere else. Shift control only thing not taken apart at that time. Then found this lost fuse and bam! There was the fuse! Hope this helps.
