Losing GPS mid run on two different devices

Hello All,

Having an issue with my Garmin Forerunner 935 dropping the gps signal mid run.

I thought this was an issue with my previous wearable (Garmin Instinct), but it has cropped up on this device as well.

You can see on the attached files where it is occurring. All of these runs have the same start and end point, but they all kick out and get picked up by the accelerometer etc. on the latter half of the run.

Very frustrating as I have not had these issues before when running with other devices (polar, apple etc.) only seems to be with the last two garmin devices I have purchased, and within the past 2 months only.

A few points on this:

EPO is current

GPS signal is green before starting

Regularly sync with Garmin Connect.

Factory Reset and hard resets tried.

GPS, GPS with Glonass, GPS with Galileo all tested (galileo causes the most issue, no significant difference between Glonass and GPS only)

One thing I have noticed - Issue seems to be occurring on runs that are all around the same time frame (ie: starts at 7:45pm to 8:00pm). This all seems to have occurred in April as well.

Any help would be greatly appreciated.
