my ps3 keeps turning off by itself and then the red light starts blinking!

its never done this before until today its done it 3 times already.the first time it happened i was on my ps3 for like 2 hours it turned off and the red light started blinking i was like wtf thats weird.so i turned it on and started laying the game i was playing before and within maybe a minute and a half it did it again. so i turned it off completely and let it sit for like a half an hour and went on it again.i was on it for a half an hour and once again it turned itself off and the red light above the power button started blinking non stop.what is wrong with my ps3?i went to playstation.com and emailed them earlyer today about the problem but i wanna know whats wrong with it right now sense it happened again.i have a ps3 slim ive had it for about 8 months i take very good care of it nothing is around it so it gets good ventilation so WTF is wrong with it?

Sounds like it's overheating to me, so you probably need repairs.
