I have made some progress. At first I thought it may have something to do with heat because 2 days in a row miner stopped at the hottest time in the day but the miners temp was approx 60C at the time and I thought it may just be some sort of hardware error shutting it down at about 60 instead of 80C.

I directed some more AC at it and it seemed to work well but eventually died a little later in the day. Every attempt to restart it failed and I got the notorious 48 asic screen.

Now I am able to get it mining again at lower frequencies. 575 worked for a little while and now I am trying 568... The loss of hash rate hurts though...
