My solar surf just started doing this when I tried to record an activity. I uploaded software, and reset settings… woke up this morning and it was off, could only turn on by plugging in. I think I’m just out of warranty so looks like I’ve got to get a new watch, not really feeling a new garmin right now after this.
I am sorry your watch has developed an issue. For all Instinct series watches that are shutting off, please reach out to Outdoor Product Support in your region.
