car died one night,thought it was just battery,got new one. on 1999 Volkswagen Jetta

checked starter and alternator also they tested ok. car ran a few days but ended up dead a few more times. We cannot figure out what is killing the battery. The radio no longer works after this ordeal though. but the fuse looks to be ok. go figure. Any suggestions??
