Hammerhead shut down, was unresponsive mid ride, with 70%+ battery life.

I was 37 miles and 8000' into a birthday ride and the screen on my karoo2 went blank, tapping the screen produces no results, and none of the physical buttons produced any results, so I plugged the hammerhead into a power bank, the power bank was discharging indicating the hammerhead was charging, although the last time I had looked at the hammer head it was at 70% battery life. After 15 to 20 minutes of tinkering with it I held both of the lower side buttons which seems to have "fully reset" the hammerhead, at which point it asked if I wanted to resume my ride, great, except that it was a ride from three days prior, which I had already completed. All the data from that day's ride was gone and there was no indication as to why the unit had gone completely unresponsive.

 So I started a new ride, and yet again, before my ride finished the unit did the same thing, going to a totally blank screen with no tapping or button pressing producing any result.

    As of late my hammerhead has also been unable to produce a route when I try to use it to navigate...

  Losing the data from this ride was disapointing, It was a very significant ride for me, and this Hammerhead is fairly new to me, I almost brought my old garmin along for such an event, but decided not to, really wish I had now...

  How common is this sort of issue?
