Symptoms vary, but seem to hold with either starting off where the car
has been soaking in the sun for several hours, or lots of short trips
(< 10KM or 6MI per leg). If car is running, engine dies and we coast to
the side of the road. After taht, everything is the same: will not
start or barely starts and chokes for a couple rev's and then dies
again. I pop the hood and go find a coffee shop or pop dispenser or
walk. Anytime after five to twenty minutes, a restart works -- car runs
like a top.

I've had the obvious suggestion done -- replace the cam shaft sensor,
and have had three more sessions since it was done two weeks ago, all
during our balmy Toronto fall weather in the last week.

What do I look for now, hopefully on the cheap side.....

my 940 did exactly the same - it often stalled in hot weather then would
start only after about 20 mins, with no problems.
After over £800 worth of "expert" work, a simple reset of the onboard
management system did the trick - All I did was leave the battery off for a
few minutes, that resets the memory and off it went - no problems now for
about 6 months...
 
Sounsds like something else that I can try (cheap too! -- if I have the
right radio code....)

Has anyone had similar problems (random death of engine) from a wonky
fuel shutoff selenoid/switch/sensor and how much did it cost?

you could simply remove the correct fuse - on the 940 it's fuse no.1...
