Epix 2 suddenly reboots

this has happened twice when saving a run.  Each time it’s messed up the recorded activity.    Also one random reboot when walking not in an activity.  Also each time it’s lost 1000’s of steps. 

Ive seen other posts about this but not sure if there is a resolution.   Saving my data is obviously very important to me or I wouldn’t have the watch in the first place. 

Thanks
