If its only while gaming, monitor and gpu refresh rate might be causing the clash of the titans!
Try downsizing your resolution and 60hz to rule out the issue.
 
Also, try using DP.

How does the display come back? Restart?
 
Is it possible that the PSU is not supplying enough power when GPU needs it the most?
