Hello, I live in Denver and we had that huge snowstorm 2 days ago.  I set up the R5 (indoors) to try to capture a snow timelapse.  I set up 60 sec interval shots up to anywhere from 200 shots to 2000 shots.  Each time I tried, the camera would stop shooting at various times during the interval and would shut off.  The longest it went was ~1.5 hrs and shortest it went before turning off was about 30 mins.  The camera didn't even save what it had shot up to that point.  The battery power was still pretty high when it turned off.  Anyone have any ideas what is happening?  I just bought the AC power adaptor to see if this makes a difference.
