from your description its clear that NAT is working but stops. This is in all probablity an issue of how the NAT tables clearance timer is set on your router. If the timer is set to never it may be hogging your memory and preventing new transaltions from being set up. Try and set the timer to clear old nat transaltion entries after say 10-12 hours.

The relevant commands are

ip nat translation tcp-timeout < secs >

ip nat transaltion udp-timeout < secs >
