I am going on vacation so I hope this helps,
Surely since its a car-borated engine with numerous vacuum lines, one vacuum line could be leaking causing this condition.
Setting that aside for now you could have a skewed T.C.C. valve. Thats
the transmission converter clutch valve. It locks up the transmission
torque converter to aid in fuel mileage at speeds above around 40 mph.
The unit is normally locked out of 1st gear. When it acts up it applies
at the higher speeds but doesn't disengaged. This will cause the engine
to stall. The feeling to the driver is quite distinctive. The normally
is a shaking or vibration felt the moment before the engine stalls, it
could feel like a shutter not unlike the sensation one feels when
driving a stick shift and comes to a stop in gear without depressing
the clutch petal. The hole thing is controlled by the engine computer.
There is a connector on the transmission which is normally square with
4 receptacles, disconnect it and drive the car as you normally would.
See if it stops stalling. If so you need to replace the solenoid. Its
located in the transmission under the transmission pan. This a long
shot but without inspecting all the vacuum lines and numerous other
sup-systems its well worth looking at a could be a fast test. Just
unplug it and drive it normally
