First off you need to figure out how you are erasing the music. I say "you are erasing the music" because it's very unlikely that its just disappearing. Make sure you are signed into the same account in itunes (top right hand corner of the main itunes store screen) as you used to purchase the music on the ipod. Next make sure you are signed into the same account on the computer. How are you syncing the ipod with itunes, manually, automatically, only certain playlists? After you figure out whats happening with your music you could contact apple at http://www.apple.com/support/itunes/store/browser/ from what I've heard they will sometimes allow you to redownload any purchased music ONCE, so decide on whether its worth it or not at this point. Finally always backup any purchases you make to a seperate location!
