iPhone 3GS Sudden shut off?

[Joyrider07]

After updating to IOS 5, my iPhone had random shutoff issue. I solved it by resetting the phone a few times. When I got 5.0.1, the issue came back, and it hasn't been solved by doing the same technique as last time.
Anybody else have this issue?
Any idea on how to fix it?

Thanks
