adjemt - Please check your email for further clarification. We may need to escalate your problem but I will need some more information to do so.
Tony,
Same thing happened to me a few times when I was using GPS only (Firmware 12.1 & GPS 3.1).
I’ve since been using using GPS + Glonass and the problem seems to have disappeared.
Hope this helps.

Have had the same problem. It is intermittent. Garmin 520 just shuts off but not on every ride. Usually I can restart it but today it died again after the restart. And, really oddly, when I plugged it in it opened at the point in my ride - around 7k - where it shut down. I saved it to Strava and it showed that the ride had occurred 4 days earlier than today’s date.
Same thing is happening to me. I bought my 520 edge plus just over a year ago and no problems until this season. It has done exactly what everyone has said previously...at least 4 to 6 times this season. Very, very frustrating. Not sure what to do. I would appreciate it if Garmin could advise specifically what I need to do.
