    Problem occurred twice whilst driving (lost all power) but car re-started immediately, unfortunately now it's gone terminal! No warning lights on dash - don't know if any error messages have been generated (don't have a reader).
    Suspect Crankshaft Sensor or Immobiliser is faulty.
    Whilst cranking the red/green lights on the rear-view mirror flash alternately - does this suggest problem is with Immobiliser?
    Any suggestions?

    sounds like a problem with the immobiliser. Try and disconnect and reconnet battery.

    Already disconnected/reconnected battery but makes no difference. How can I disable the immobiliser?
