this was my initial guess: if the connection works for 4 minutes and 
then drops all of a sudden then I suspect there's a firewall which is 
detecting then blocking openvpn traffic.  OpenVPN does not disguise 
itself in any way (not even TCP port 443) so if you need to duck below 
some government firewall then I'd suggest you use other means.

See if you can set up a simple webserver / port listener on the PC in 
the US and then connect to that (not using the VPN) for more than 4 
minutes. If not then there's another networking issue involved.

HTH,
