FXC No Hashrate

[Burger]

Mining good for a couple days and then the past couple hours I'm going to zero hashrate. Miner looks fine, accepting shares. I know after a block sometimes the rate drops but I have never seen it completely drop like this after 3 days on this coin. Do you think the difficulty is set too high? Should I put in a custom difficulty? I have these gpu's split mining with another pool so that's why my hashrates look halved.
