Anyone have problems with missing data on an Edge 510?

This evening for example everything on the display looked normal from the start, power, hr, speed, time. Finished the ride with right around 2 hrs showing when I stopped and saved. Downloaded it and on Strava and in WKO it shows a straight line from start to about where I was at 30 min on the map, with all data blank. Then normal data and map, and a 1:30 ride time.

This has happened twice in the last week. Unit is less than a year old and has been flawless to this point.
