Have you tried another torrent client such as utorrent or Vuze?

utorrent is my torrent client and has never let me down. Are you in the U.S. by any chance? I know that some Internet Providers are currently monitoring downloading activities and are dropping connection speeds to almost dial up speeds for those who exceed a certain data limit. When they put the brakes on your download speed drops and breaks up intermittently.
Try utorrent...If it still does the same thing then it's your IP that is causing the issue. Hmmm...now that I think of it...you may also have an issue with your firewall. Make sure that the firewall is set to allow the connection for your torrent client!
Hope that helps!
