Random disconnection during Firefight

Was just in a match of Warzone Firefight and our team was about 90 seconds away from finishing our fight against Hunter bosses. While respawning, I got a random black screen of death and then next thing I know, my entire Halo 5 game minimized and it completely kicked me out. I raged for about 10 seconds and remembered that this is Halo 5. I have a completely open Nat type and I had a buddy in there that experienced no problems.

Has anyone experienced this random complete disconnection? This is about the 3rd time it has happened to me while playing matchmaking. I’m quite frustrated with this issue with the game.
