ride stopping partway through

I have an apple TV and a Sirus trainer. I was riding Nicasio Valley this week and twice it stopped and wouldn’t go forward. The timer kept running but I wasn’t moving and the distance meter also did not move. Pausing the ride didn’t help. I ended up clicking save for later and restarting and that worked the first time. The second time that didn’t work either. Luckily, the second time I was about 30 seconds from the amount of time I wanted to ride so I just pedaled for 30 more seconds. This hasn’t happened before but would be super annoying if I were doing a climb. THis time I was just doing a recovery ride.
