One Click Miner issue 1 of 4 cards just stops working

About a week ago I started mining VTC with One Click Miner. First day it worked great. I stopped for a few days to focus on something else but wanted to return to VTC. I starting mining again last night and woke up to see GPU 0 has stopped mining.

I rebooted and everything worked fine for 10 mins then GPU 0 stopped again while the other 3 cards continued working fine. I would close and restart the miner and the same thing would happen GPU 0 would stop after 10-14 minutes.

I took all OC settings off GPU 0 except TDP at 80% and again the same thing happened. All 4 cards are MSI GTX 1070s Gaming Xs bought around the same time. GPU 0 handles Zcash with no issues and a much more aggressive OC.

What could be the reason just GPU 0 stops mining out of the blue?
