Ipad blanked out.

[RuralWarrior]

Sometimes my Ipad2 randomly blanks out when I'm on a page or if I click on something, the screen just goes blank and returns to the home screen.

This is particularly annoying if you're writing something and everything is lost.

I use Safari and google as a search engine.

I've reset it before by holding down the on off button. Any advice on what I can do or what's going wrong?

Thanks
