Minn Kota issue

[Kent]

I just started having issues with my Minn Kota Terrova.  When I have had it running, either moving to a new location or when using spot -lock, after a brief time, I get the message "Motor not found" on my iPilot Link.  At that point the Terrova stops and if on spot-lock, spot-lock releases.  After a brief moment it links again, but it doesn't last.  I tried running it, at home while the boat was on its trailer, and I experienced the same issues.  Interestingly, I ran the iPilot Link app, on my smartphone, simultaneously with the iPilot Link handheld unit, and they both gave the "Motor not found" message at the exact same time.  I also tried using spot-lock and then turning off my iPilot Link remote and the iPilot Link app, and the Terrova would turn the prop off and on, for several minutes, (trying to return to the spot-lock point) and then the unit shut off.  To me, these actions would indicate that the problem is on the Terrova and not on the iPilot Link. I also found it interesting that when I used spot-lock, while the boat was on my trailer, that despite the trailer being stationary the iPilot Link showed that the Terrova had moved as far as 13' from where it was when spot-lock was initiated.  The Terrova would be aggressively running and turning the prop trying to get back to the GPS point, while sitting stationary on the trailer.  Does anyone have any suggestions on what I need to do to get it working correctly again?
