Running out of steam
 

My 944 N/A wants to die and refuses to start when it has been driven more than 10 or 15 minutes, leaving me stranded on any roadway that I have to stop.

Has anyone had this warm engine no-run problem.

When it runs, it purrs like a kitten. Fresh cap, rotor, wires, plugs recently installed. Passed CA smog with flying colors.

Pop in your spare DME relay and see if the problem resolves.

guy on rennlist had the same prob... could be a few things. His was leaking injectors

Mine was negative battery cable that wasn't tight enough?

Other possible causes:

1) Reference/Speed sensor are dying (Connectors or the actual sensors)
2) DME computer has bad solder joints

Others as well, but those come to mind right away.
