My PS3 keep shutting down when I play Dead Space 3

Thanks for the replies guys I don't think it's a problem with my ps3 cause I play games that have come out recently and have been out for years and the only other game I have problems with is battlefield 3 but I know everybody has the same problems as me with that game but even if it was my ps3 it's just pointless to buy a new console when the ps4 is so close to release
