More problems... non-starter and cutting out.

[Lawrence]

It's only cut out once, but that was more like hitting the killswitch than fuel starvation - it just died, no spluttering/rough running.  It has failed to start twice now when leaving petrol stations, so there shouldn't be a vacuum immediately after filling up.
Fairly sure it's electrical, got a feeling it's plugs or pump but will have to do some investigation tomorrow.
