Motor runs great except - - -

3 or 4 times recently, during a cold start, when leaving the dock; within 100 yards it throws a over-temp fault.

I check for telltale, it's there and strong.
I turn off motor and immediately restart it and the fault is gone.
Motor runs fine the rest of the day.

I know that there is an "absolute" over-temp fault and a "gradient" over-temp fault.

My conclusion is - the mechanics are fine (it's not really over-temp).

Could it be a bad sensor or bad software? I suspect the gradient fault is being set for some reason.
