I had a user with similar symptoms as yours. He was using a usb cellular modem (for at&t) and recently his secureclient connections would drop him 5-20 seconds after he connected. I looked at the logs and it appeared that his client was changing IP addresses, I informed him how this would cause the client to lose connectivity until he reconnected and that he should contact his ISP.

He spent about an hour on the phone with his ISP, the problem ended up being in the accelerator program which was part of his package with the modem. The particular program he used (apparently there are many) is called ByteMobile Acceleration client which is installed on the laptop as part of their Communications Manager application. Instead of uninstalling the program their support had him go into Settings for Communication Manager and change startup type to manual from auto, under advanced tab changed from a standard optimize all supported protocols setting to a custom one where all protocols are moved to the unoptimized column.

It sounded like this was a known problem and sounds eerily similar to yours.
