Instinct 2, Auto Pause feature not working correctly while in Hike Mode.

Instinct 2, Auto Pause feature not working correctly while in Hike Mode.

I have an Instinct 2 that I set to Hike Mode and it won't restart after an "AUTO PAUSE" event.  I started hiking and in 1.8 seconds it stopped.  I kept moving to see what would happen and nothing.  I had to select "resume" for it to start again.  20 minutes into the hike, I paused and it stopped as expected but would not restart when I continued my journey and I traveled over 500 meters.  I had to disable the "auto pause" for rest of the day for the watch to work correctly.  Battery is at 50% and in clear view of the sky.  I tried shutting if off and restarting with the same result.  Any ideas?
