Clean the pilot out , clean the injector it could have a small blockage , causing it to burn soft .

The batteries are to low for the auto charger to work so either replace batteries or have them load tested to see if they are any good. Personally I would replace them.

A circuit breaker is recommended but not included. Do you have a circuit breaker? If there is a fuse it should be inline with the battery wire.
See link below.
Fuse and Circuit Breaker Overview

I have a terrova with i pilot same thing happened found out it was the remote, if thats not it then you will more than likely have to send it in for repair.

have the motor tested
could be brush or bearing problems

I have the same problem. Do you have a solution for it yet?
I do think it has to do something with decreasing power from my onboard accu. The first hour(s) sailing I don't have any problems, but after a while mine is jumping to STANDBY too, and the periods between become shorter, until less then 5 minutes.

Does the unit work without the auto pilot? Sounds like the auto pilot or the reciever is not functioning correctly.
Check and make sure the unit is grounded properly, you may need to run a test ground wire from the battery to the motor istelf to check this.
This is simple to do and takes 15 minutes. Starting in the battery compartment feed cable into the split-loom and continue feeding until reaching the control panel. Pull an extra 5 foot of cable and open dry hatch in rear by motor feed cable around and out to motor connections., Good time to check any circuit breakers
Try cycling the auto pilot though the modes.
there are 3 modes
to cycle through each mode
hold down the + and - key for 2 seconds
this cycles you to the next mode. Last but not least, try turning the unit on and spinning the prop by hand to see if it takes off, the motor migt be bound up slightly or have a bad spot on the brushes.
