I had the same problem with the same model iPod. At first my laptop would not recognize the device; after a while it also stopped taking a charge at all.
First see that you're using a cable of at least 1 amp output. (Many are only .5a.) Even though my iPod has been repaired (see below), I still have to use the 1a to get it to charge and connect.
If that doesn't fix the connectivity problem, it's probably the same issue as mine - some of the 40-some connector pins in the iPod's port were apparently bent and not making proper contact with the charger pins. (Lesson learned: I'm now very careful to plug it in perfectly straight.) Had to call in the big guns for that one: I found a parts-only, identical model iPod on eBay (ensuring from the seller that the charging port actually worked), had a geek-inclined relative swap out the non-working battery and hard drive for my own, and have had no problems since. That method is iffy and depends on you or a friend being able to mess with it, but it's a lot cheaper than buying a new iPod.
Hope either of these tips help.
