Engine intermittent cut out

I still have a problem with a intermittent engine cut out on my G13BB I've asked the question before but now i have more info i have fitted a air fuel ratio meter i can see when engine cuts out it go's off the scale leen so it's sounding like the fuel is cutting out anyone got suggestions or experience in this only happens very intermittently

2 things that usually cause intemittent cut outs:
A faulty lambda sensor will send duff signals to the ecu and the ecu will pause momentarily before reverting to a default fuel map. This will normally produce an error code.
The cam or crank position sensor (cam sensor on your particular model) The engine relies on the signal to know the speed and position of the engine. When the signal stops or is interrupted the ecu assumes the engine has stopped so cuts fuel and ignition. This doesn't leave an error code.

Thanks Busta but I've replaced both G13BB only has cam angle sensor can electrical relays give intermittent faults is there one for fuel injection what is the wire colour code i don't have access to manual now

I had an intermittent cut out problem on my Gen.4 and eventually traced it it over filling the fuel tank.

Might be getting a bit closer to sorting engine surging when i leave battery disconnected for a while it resets and runs well for about 30 to 40kms then back it's old tricks that rules out a vacuum leek I'm guessing somthins going out of range?
I thought i fixed it before when immobilizer packed it in but i had battery disconnected when i rearranged the wiring
