It seems as if the GPS fix gets lost occasionally when the issue happens but it comes back within a minute or so. When the fix becomes valid again the location being reported is still incorrect. The 3 images show the modem details when gps fix goes from valid to invalid. Even when showing a valid gps fix the location is incorrect. In this case it is giving a point approximately 70 - 100 miles away from where the correct location should be.
