  I'm shocked -- *SHOCKED* -- to hear of a problem on a Verizon feed.  ;-)

  Everyone else has posted good info.  Do what they said.  One thing
to be certain on, though: If you have an active session for that
period, it works fine, right?  If so, that would rule out a DHCP lease
or PPPoE session expiration.

  You might try running a "ping" to the SSH server continuously in
parallel to the SSH session, and watch for any disruption at the same
time the SSH session dies.

  You might do a "before and after" traceroute to see if anything is
changing in the network topology on the route.  That might uncover
something.  Also look for RFC-1918 addresses on your connection or
along the way.  Those will often be a sign that NAT is in use.

  Don't use Verizon?  ;-)
