Samsung S6 Tablet crashing/closing mid race (not in workouts)

Hi, I have a samsung s6 tablet. Runs fine when im riding on my own in zwift and never have a drop out. However last night it closed on me 8 minutes into a team TT. This is the 3rd time now its closed in race. I used zwiftalyser and no connection issues. The only thing i can see is it maxed out at 60fps just before the app closed. Is this the issue and the device is just not good enought to run a race?
