GPS issue with Garmin Forerunner 645 M

I had this issue where my Garmin Forerunner 645 M will just stop tracking data during a run. I don't see any unnormal behaviour during the run but when I sync the data there is a part of the run missing in the data synced.

The activity can be seen here https://connect.garmin.com/modern/activity/9002112967

I exported the run as a TCX file and watched the data, and I can see that there is a jump in time between two laps and also a jump in coordinates. There is missing data for 34 minutes.

How can I avoid this from happening again?

I've had this same problem happening a couple of times now. While running there doesn't seem to be any problems with the activity. When I get home and sync there is a gap in the tracking data. Very annoying. I've had this watch for 3 weeks now, and I like it overall, but starting to regret the purchase since the main reason was to use it while running.
