VT V6 turn ignition and everything goes blank fault.

So as the title says i'm having this problem. i have heard a relay clicking and replaced it and same thing happens. this is the LPG relay and the car doesn't have LPG.
the battery and Alternator are working fine, and the problem is only intermittent. I have checked the code by bridging and it has given me code 12 which means Satisfactory Operation. obviously not!
it happened this morning and i have flicked all the relays and then it just works. i cant seem to find anything in the recall area on this so if anyone has any ideas i would greatly appreciate your time!

All i can think is that it must be something to do with the BCM.

Thank you for your time.

9. Some starting issues can be cause by the BCM (Body Control Module). The BCM may electronically lock up or freeze (caused by voltage spikes), which may restrict starting, locking and unlocking etc. Some BCM's were returned under warranty because of these issues. In some situations, the key reader circuit ban be a potential source of a voltage spike, and a grounding patch harness was released to reduce this occurrance.
