Its a really hard on Tabetha - i can never make it do it lol When it does cut out - sods law its somewhere you really don't want to be stopped:P
I had a look at the phase and crank sensor connectors and both look fine - Loom sides too.
Drove the car again, did a few miles flat out and it didn't turn off. So hopefully its sorted its self out:P
It has however put me in the mood for a new loom. As i can see this being the start of many many annoying issues
