Unfortunately i'm not on a stock Samsung rom anymore, so i can't remember if there is a power saving option that would allow the Tablet to power off after your given time.
Neither of my two tablets have any issues like this i am afraid.
You could always try performing a factory reset on the tab. This 'will' reset it back to stock, so any apps, mail accounts etc will be lost, unless they are backed up to your google account.
If you do not want to attempt this, then you can install Kies on your PC and update the tablet to the latest version of ICS [if available] for your region. Kies will automatically inform you if there is a newer version available for you.
Hope this helps.
