The Garmin autopilot on the EX works great, most of the time. It is controlled through the G3X. But it randomly just quits at intervals of perhaps 20 minutes or so, with the usual 'beeps' and the AP image turning red. Turn it back on and it is good to go. This happens in most any conditions: smooth air, cross wind, bumpy air. Before turning it on the plane is stable, trim properly set.

I am looking for any ideas why this is happening.

The settings as to gain, airspeed, etc. seem to be appropriate and working as they should. The mechanical connections with the servos are in good order as well.

The operating system is current as of July 2019.
