Game Black Screens and Freezes While Playing

This has happened a couple of times today. I was playing a map and more than half way through the match my game black screened and was frozen. I was in a party with friends each time and they could not here me and the only way to get out of it was to close the game. I relaunched it and didn't have the issue for about another hour. I have had the game black screen a couple of times in the past, but this is the first time it's done it twice in one day.
