Mid run - I noticed the screen froze and stopped updating time and distance.
I pressed GPS button twice and it resumed.
Also - this was during a "Do Workout" function - and the workout screen did not appear when I scrolled through screens.
It only appeared again after I pressed the Lap button.
In this same workout - the GPS reading was completely off at the beginning. Starting point of the workout was wrong, and even the running direction was reversed. I ran east - it recorded west.

I had a similar GPS miss a few days ago as well. Link:
