    Now, just to be sure here, you have a diesel so when you say running, is it running AS IN running? Or Running then Runs a bit then dies?

    If its the latter, sounds like you are experiencing a situation we used to call dieseling or run-on, This was usually caused be a few easy to fix things idle set to high, vacuum leaks, fuel mixture set to rich, timing not set right. Now if the mixture is set rich for very long a carbon will build up in the combustion chamber and raise the compression ratio necessitating a higher octane fuel to combat pinging or what is known as spark knock.

    If its the first, then my take on it is a faulty ignition switch
