It started erratically connecting and disconnecting itself when plugged into my iMac about a week ago and i'd get "please eject your ipod before disconnecting" messages. It got increasingly more erratic until yesterday when it became completely unresponsive and won't appear in iTunes at all. It does flash red and beep three times with headphones plugged in when play is pressed but doesn't play. I just discovered this evening that it will momentarily flash green when I hold down the play button for 3 seconds but I've searched all over and can't find out what this means. Not sure if the battery is toast or what.
Edit: It's a 4th gen.
