I have had similar issues with my EVGA 980 SC card. I finally loaded EVGA Precision and dropped my GPUs core clock by 105mhz and bumped my fan speeds up. Problem seems to be solved. It sounds like your card is crashing, which could be a lot of things; too much heat, not enough voltage, bad overclock, etc. If it's a year or more old, you may just need to blow the dust out of your GPU air paths in the heat sink.
