getting disconnected and returning to the main menu for hours

keep getting disconnected back to the main menu for hours, i am playing from eu but its not a internt or a ping problem. i have not found a viable solution and its taken me a good hour to even finish the prolouge for me to disconnect about a mission after getting to the main ship. i have played the jp version before and had no such problems.

I have the same issue. I suspect it has to do with xbox live because everytime that happen to me, it ask me to login again.
