850 T5 stalling

Good day gentlemen/ladies

I had a bit of a scare whilst driving on the highway at approx 100 kmh. The
car stalled/ switched off.
I was off throttle and when I tried accelerating ...nothing. I pulled off
onto the emergency lane , turned the ignition off, selected park and tried
starting
The car started on the 4th attempt.
I have replaced the turbo control valve. The MAF sensor might be a culprit,
but I suspect the gearbox position sensor( inhibitor switch). My reasoning :
the gearbox on startup goes into winter mode. I rectify this by engaging
gears , letting the oil settle a bit.
(gearbox has been flushed and oil changed) This problem has been with me a
while.
Is the inhibitor switch the same as the PNP switch ?
Could this cause the ECU to switch the car off ?
P.s the car is a 1994 850 T5 auto
Thank you

I have this problems , not often, but occasionally and not when
accelerating...usally in Park ...have a 98 S70 t5...have no answers and
the codes my shop ran and pulled did not indicate a specific problem.
....they did mention turbo valve connections though.

Re: 850 T5 stalling

Oh yeah...when my car stalls it starts right up but need to accel
somewhat firm....also have noticed this clicking sound in Park /idle
and then the engine revs alittle ...then does this over and over like
clockwork...did not do this in cold weather (its 85 degrees here in the
Balt-Wash DC area today) just stalled occasionally.

My problem never re-curred (4 days now) but its a pity I cant replicate it
on demand.
Just scary not knowing when it will re-cur , especially with the wife the
driver most times.
