One (or more) of the firewall devices between you and the remote server
is timing out your session. To stop this happening you need to use the
ServerAliveInterval setting.

For example, drop this in your ~/.ssh/config, or if the file already
exists, tweak it appropriately:

Host *
ServerAliveInterval 60

I often have these two configuration items in there, too, but YMMV:
ForwardX11 yes
Compression yes
