This sounds like a bad connection or sodier joint that you knocked lose
when you moved your system.  Thermal expansion probably causes the connection
to break after your amy gets warm.

I'd suggest that you ground yourself and reseat every chip that
is socketed.  You could also do this with the circuit board that is supported
above the main board (kick start board?).  Remember to remove the screws first!

How do you know?  If the memory goes off line, after your system is depending
on it, it will guru.

Remove your memory board and see if it still gurus after it's warm.  If not 
then it's probably your memory board or it's connection with the Amiga. 
(The latter is more likely).  I have a lot of problems with a memory on
the expansion connector.  Cleaning the edge connector by rubbing it lightly
with a clean pencil eraser seems to help sometimes.

Did you run the test after you started having gurus, when your computer
was warm?  Leave it run for a few hours (or days).

One more thing - Make sure you fan is still running.  On the 1000 it's so
quite you probably wouldn't miss it if it stopped.

If you aren't comfortable playing with the guts of your computer, haul it in!

I've got one too.  (An Altair 8800B)  It makes you appreciate the Amiga!

	Good Luck
