It's most likely a problem with your save file ( online profiles are still ghost saved to your harddrive), their servers ( which would be fixed
already if it was due to the authentication during log in) or it could be an xbox live issue.
Microsoft handles all the xbox live servers, all the devs can do is submit updates and such.
I've tested this with my son's account, played a few local matches, turned the console on and off, checked his online profile and it's fine.
ETA: I suggest using another console to grap your LIVE accnt and see if it shows up on another console. I've seen weirder things.
YOu can also copy and port your save to USB; delete the file from your harddrive and then re-instate it.
