(I'm writing this with a 9000 in mind... assuming you have the 16 valver
with the bosch LH injection system, it's pretty similar, I don't know what
systems go with the 8v motor.)
I suffered a similar problem with my 91 9000 over 6 months or so; we
replaced a number o7f bits, including the ignition ECU (Bosch EZK), which
I'm fairly sure aren't applicable to you. (To the best of my knowledge, the
separate EZK box style ignition was only fitted to 9000's for a small
period)

Anyway, it turned out to be a problem with the crankshaft position sensor.
The clue in this case was that as soon as it stalled, even though the car
was coasting down the road at 70mph in gear, the tach was reading 0. Again,
this probably doesn't help with the 900 as I don't think the tach is driven
in the same manner. I hesitate to suggest you change the sensor, as it's
unusual for them to fail, particularly in this intermittent manner, also
they're difficult to do - the crank pulley that drives the serpentine belt
has to come off. However if all else fails this may be a good place to look.
Next time it's not working check for a spark at the plugs - if there is no
spark it's the ignition system. If you have a spark, chances are it's fuel
related, though the spark could be happening at the wrong time.
