I have this problem on a regular basis, and its exceptionally frustrating! The watch app will just stop tracking altogether, and the calories/heart rate on the phone app get frozen. I can complete the workout on the phone, but the end calories burned that gets imported into Apple Health is wrong. Restarting the watch app doesn't work, and I can leave the workout and start it over, but I lose all the progress I've already done. This is such an annoying bug, and has been happening for over a year!
