Connection to Xbox lost

About two or three times a week, I will get booted from a game on Halo 5 and it will say: Connection Lost your Xbox has Lost connection. It always happens when I use a rare boost card. Always. I earn those the hard way and then they are lost. It’s only Halo 5 servers. MCC servers don’t do it and neither does Halo Reach. So maybe instead of saying your xbox has lost connection it should say: Connection Lost, We apologize but our servers have lost connection with your xbox. Your current boost if using one will be lost. Sorry once again. 343 team. That is what should be said.
On another note: I want my boosts back, please.
