Mine' been doing this for a while and I've just put it down to the iPhone crashing, like any computer does.
It usually happens when there's a large program running or I have a lot of browser windows open.
I'll be using it and the screen will just go blank.
I'll push the home button 3 or 4 times and nothing happens. Then, after 30 seconds or so, the white Apple logo appears and the iPhone starts up again with everything closed,
