Edge 130- random shutdowns and “ ride in progress” reboot?

Hey all- seeing a few people having  this issue: Since my 130 updated to 3.40 I’m getting random shutdown / restarts whilst riding- 3 in 25km today! Here’s what happens: 

From normal data recording , Devices flashes Garmin screen once momentarily, goes blank, then full Garmin screen startup. Cadence / speed sensors reconnect , then I get a “ride In Progress” screen. I have to manually restart data recording and lose whatever distance i’ve Covered during the reboot. It’s really annoying and it’s going back soon unless it’s resolved..

it COULD be related to periods of non-pedalling- I.e going downhill for a while... anyone have any ideas/ solutions ? Thanks!!!
