iPad can't use safari, App Store, etcSafety

For a couple of months now my iPad has been unable to do much of anything on Safari or connect to the App Store. If I restart my iPad it will work for a little while then stop. I know its not a connection issue because I can use apps like Facebook or other apps that require an Internet connection. Any help would be appreciated! My laptop just died so it looks like my iPad will be my "computer" for a while.
