Could be crankshaft sensor , often fails when hot then fine when left to cool / go cold .

Thanks for the reply ..... Would crank sensor throw up a fault code or warning light , do you know ? I'm starting to think some sort of immobiliser fault....as it drives perfectly when its running...no cutting out or rough running.... what a pain...

A crank sensor would normally throw a code , but being intermittent might not .
