VN stalling

[totality]

hey guys...
i just got a 91 model VN berlina wagon V6
very good condition apart from a few things.
the car will start and actualy run very well...idles nice and smooth and seems to have a bit of power for a 6
but after about 10 minutes it will stall...
the previous owner knew about this problem and sold it to me cheap cuz he bought a new car and didnt want to deal with this problem.
things that were changed to my knowledge by previous owner were

Fuel pump
Fuel filter
Harmonic balancer
Water pump
New battery

any ideas on what it could be??
i havent checked plugs and leads yet but they obviously work as it does run....
any help would be great

Try a CAS as it can fail when it gets hot.

Yeah is will be the cas if the car is running along just fine than completely dies it's not really like a stall it's just total instant power loss from any revs

[azkwazere]

yeah try CAS(or Crank Angle Sensor)

Cost about $90 Dollars...

i cleaned out the throttle body and it was F***ing filthy aswell as the plenum.
while i was there i removed the bellmouth but im gonna put it back as my car is running rougher without it .
after doing the throttle body the car kept stalling.....
so i checked for fault codes and it came up as 41 which is CAS
so on thursday ill go and get another one and change it over....
i can get one from holdens for around 60-70 bucks with holdens discount so hopefuly thats all thats wrong with it.
thanx for the help
