I had a similar problem.  I'm not sure this will help, but I'll
relate what happened.

My 3B1 (40MB/1MB) was running happily in my basement when my wife
got a court order to throw me out of the house.  (Long story, suffice
it to say she abused the laws and I'm 98% sure I'll get my kids and
house back in the final showdown.)  She then unplugged the 3B1 without
so much as turning off the power switch.

It sat there for 2 weeks while my lawyer tried to get her to release
the machine.  Finally they reach agreement, and she brings it up into
the garage and lets it sit there for hours.  I pick it up, carry it
to its new home, set it down, and plug it in.  Friends are warning me
about condensation, but it's already coming up.  It boots fine and
goes into its fsck ritual.  I'm still carrying stuff in, and 30 minutes
later I check on it, it's tripped the circuit breaker.  Repeated attempts
to boot it show it comes up fine, but after 4-20 minutes, the breaker
trips suddenly, without warning, and it shuts off.

Next day I open it up to check that the fan cable is still connected,
which it is.  I run it with the cover off, it runs fine.  I put a fan
blowing on it, it's happy for days.  Then I put the cover back on, and
it's still fine.  I never did put the screws back in, but the cover's
on tight, so I doubt that matters.

I do notice the fan is a strange beast that likes to change speeds if
I look cross-eyed at the box.  Moving it especially changes speeds.
I suspect that the combination of moving, temperature change, humidity
change, and phase of the moon were all involved.
