Yup, tried "learning" the old remote. No go.

Called MinnKota service. Said they hadn't heard of the "shutting off while trolling" problem. Advised me to take it to repair center near (1 hour away) me for warranty repair.

The "auto off" feature is set at 30 minutes. But that shouldn't be a factor since the motor was constantly adjusting position in the anchor lock setting. The auto off is only for when the motor gets no commands for a set period of time. I used it for hours yesterday set on the 30 minutes setting and never had to "restart", reset, or reboot" the remote.
