We had the same thing happen to us twice 12 months ago and after a full checkup was told one of the coils was faulty so to be sure I had the mother board and all 3 coils replaced and haven't had it happen again.

First thing to do would be check the ECU for any stored errors. The thing with coil failure is it usually only affects 2 cylinders, which would make it sputter and lose power but not die. The chance of losing all 3 at once is minimal unless you lose the 'motherboard' that sits under them, which is called the DFI. Were you running on gas of fuel at the time?

If it just died instantly, may be it could be an ignition problem or even a faulty inhibitor switch.

Good chance its the crank angle sensor on the way out. They play up intermittently when they get hot, then start working again after cooling down a bit.
A loose connection where the wiring loom attaches to the DFI module (located under the coils) is also a possibility.:)

Fuel pump or the relay for the fuel pump something to look at as well.

From what youve described Id also say its a faulty CAS-(Crank Angle Sensor). Very common problem with the V6's. If it turns out to be the problem, try not to buy a cheap aftermarket CAS, buy a genuine holden CAS and it wil last another 10 years instead of 10 months.

If your "check engine" light came on when it stopped it will have thrown a code.
But crank angle sensors often don't throw one when intermittently failing.:supersad:
Same thing with fuel pumps.
So yeah...process of elimination.

went to the dealers today and they tell me that its a fuel purge hose?no errors were found,
so does this sound right to the experts on here?

i have my doubts because of the way it stoped instantly.i just hope they are right.
thanks again gaz.
