Sounds like you have a firewall with a very short activity timeout
between you and the remote system. You need to fix the firewall.
(The timeout is likely associated with discarding the NAT mapping
for your connection; you may be able to adjust it in the firewall's
NAT settings.)

Or, if you can't do that, program your application to send dummy
queries every so often ...
