I had a similar problem a few times with our KFPS-2.  It also has the
hardware mod with the moved capacitor, and showed exactly the symptoms
described in Technical Bulletin #1 which documents the hardware mod.
In my case, the K-box would run just fine and flake out every 2-3
weeks.  It wouldn't respond to pings and the FastPath Manager couldn't
find it.

A nice lady in Kinetics' tech support group (sorry, can't find her
name) thought it could be a bad RAM.  She suggested cycling the power
without reloading the K-box the next time it crapped out.  If that
worked, the capacitor might be bad or have a bad connection.  If not,
probably bad RAM.  The K-box has worked flawlessly since then (3 months
now), so I haven't had a chance to further diagnose the problem.

FYI, we run KIP 09/87 and CAP 4.0 with patches 1-15 and some local mods
to lwsrv and papif.  I'm planning to upgrade to the new KIP/CAP stuff
later this summer.  Please mail/post a warning if you discover it's a
software problem.
