We were seeing something similar to this a while back, SSH sessions to or from outside our network were dropping after some period of no activity (which may not be your problem). Eventually we found that the Cisco PIX on our perimeter was set to kill idle sessions sessions after a certain period.
We were able to resolve this by editing /etc/ssh/sshd_config and setting the ClientAliveInterval to a non-zero value. In our case we set it to 240, which caused a "ClientAlive" request packet to be sent every 4 minutes over the encrypted channel as the idle threshold on the PIX was set to 5 minutes. This resolved our issues, perhaps it might help with yours.
