Fenix 8 Pro (43mm AMOLED) blue triangle mid workout

I’ve had my Fenix 8 Pro for about 4 months now. At least once a week it will reboot mid run and display a blue triangle for 1-5 minutes. I have reset it multiple times, assured software was up to date, connected to Garmin express, and do not use any custom faces or data fields.

Any advice or help would be greatly appreciated, I have a race next month and just can’t trust the thing.

EDIT: 47mm
