Defective GPU? Or driver issue?

I just installed a MSI Gaming X 1080 Ti on my PC (had a Hybrid Titan X earlier, moved to a different setup) and I'm having some issues. Every game runs great, stock or overclocked, for about 10-15 minutes. Then for no particular reason I can tell, the framerate just drops from solid 60 to 20fps (it varies from 15-20 fps, and wont go any higher), in every game I play. I have to restart the computer every time to fix this issue.

This happens even if I don't even do anything, and just idle in a game for 10-15 minutes. I know the MSI Gaming X has a stock power limit of 300W or so, so is it possible that a random draw spike is causing the performance to crash? The display driver doesn't crash, and nothing else seems to be changing, the framerate just randomly crashes some time after for no particular reason. I've already tried cleaning drives with DDU. The only thing I can think of is the GPU internal BIOS must be going into protection mode or something from too much power? I have power limit at 117% earlier, and dropped it to 100% but it's still occurring, including overclocked or just at stock clocks.

When the framerate crashes, MSI afterburner reports the GPU is at 100% utilization and the clockspeed stays the same...but the power % drops from 85%+ to about 60% and just gets stuck there. Is this the internal GPU BIOS is limiting power output, some kind of limited protection mode?

Using an EVGA p2 1000w and my gaming temps are about 70-73c after about 10 mins of gameplay. Once the framerate drops to the 20s the power usage drops to 60% and the temps start dropping slowly and settle in the mid 60s.
 
What is the performance cap in gpu-z. Can you also check in nvidia control panel that you have max performance enabled for the game title you are looking at. Obviously check everything is seated correctly (re-seat gpu) and occasionally a power cable pin can push out the back of the connector
