Oy!  Gotta rewind the tape on this one!  Ah, well.  The A1000 expansion
port is a strange beast.  LOTS(!!) of problems started to occur with a number
of systems as soon as you added _anything_ to the port.  The most common
problems were caused by two things: weak (low drive current capability) PALs
and/or poor grounding of the PALs on the Amiga.  Your shop will know what
I mean.

Commodore changed vendors a couple of times with the PALs.  One of these
vendors' chips didn't have the oomph to drive the expansion port properly,
hence there were all kinds of weirdness going on.  Since you mention the
fact that it warms up then poops out, I'd suspect that you have one of the
grounding problems (either cold solder joints or inadequate grounding of
the PALs).  Once the system warms up, the connections get flakey.

Trying to fix either problem is not for the faint of heart.  If you're
qualified to wield a soldering iron and have good intestinal fortitude, you
might have a go at retouching the grounds on the PALs as a first try.  I
would __STRONGLY__ suggest that you take your baby to the shop and let them
do it.
