My first guess is that something is screwing with your routing. Perhaps
a DHCP renew is resetting your routes to go via your local network
instead of the VPN.
Show 'ip route' output when you're first connected, and when it's
broken.
Try capturing traffic on the tun0 interface when it's not working. Are
the packets even being *sent* that way?
