big red 50a is the right one, so thats one problem sorted 

Now moving along... what rpm does it idle at with aircon on AUTO and what speed with aircon on ECO ?

If I was you I'd be heading to the nearest member with a TECH2 and have a proper diagnostic run.

Looks as if the crank sensor could be a bit of a mare. I may be able to get access to a ramp to do this. Where is the best place to get the parts if needed?

Crank sensor is not a bad job. It's up by the oil filter so not too hard to access. Just need to pop the front passenger side on and axle stand.

I would only go with a genuine GM crank sensor. There are several different styles of plug on them too so getting the right one is important.

Could have a look with the Tech 2 and see if the MAF output and fuel trims look OK.

Maf would not/should not cause a stall as it reverts to a default map if it fails and the pre face maf is said to be bullet proof anyway. Add in that maf codes are often thrown spuriously when crank sensor fails with no 19 code, and that the car cuts out when not in tick over, then as said, your looking at a crank sensor issue.

Also as said, it's a simple job, just involves finding the correct plug at the back of the plenum, and jacking the car for access under the pass side by oil filter housing. There is a guide also.

Cheers Guys, I knew I could rely on the OOF!

Looks like I need you Kevin and your box 'o tricks. I will search for a Crank sensor Today, any suggestions for a good source?
I will check out the idle and aircon thing also this afternoon.

A Vauxhall dealer, Pm to AndyC for best price.

Yep, what that man said - use only a genuine Vauxhall crank sensor as received wisdom is that any other make will last months at best..

All advice greatly recieved.
After huge time gap,(read lazy), I have fitted a new sensor and all is good!
Thank you to AndyC for the help with the correct Sensor, bit of a cross over year! on my reg No.

Thank you all! I can drive for more that 10 minutes without fear of sudden loss of power and certain death when traversing big roundabouts,(stopping on them in rush hour, is not much fun).
