The game turns off

Early everything was allright, but now sometimes after 1st or 3rd quarter (after showing coming games) the game turns off...How to fix it?

yep happens in NBA today mode since entering season mode I had no crashes so far
NBA today mode doesnt like .ros files only .LFG files

My NBA 2K11 use to turn off after 10-15mins, I had it installed on a drive separate from my OS, reinstalled it on my C Drive and never crashed again.
