The thing which is strange is the way the OP describes the problem as being one which 1) only occurs when the engine is hot, 2) doesn't want to restart when hot but restarts perfectly when cold. If a fuel problem was causing the engine to stall I would suspect it would not restart easily when cold since it still has to prime itself. I'm wondering if the problem isn't electrical after all? I would say 99% sure it was not fuel/air leaks if the problem occurs with a full or near full tank of fuel...if that was confirmed I would concentrate on electrical issues.

On gas cars there is a crank position sensor which frequently fails and causes exactly the symptoms he's described. I don't know if our cars have an equivalent sensor although there must be some sensor which feeds the ECU with engine speed data and to provide a signal to the tachometer. Does anyone know where the engine speed data is taken from? The fact that he got a code about that may not just be a red herring.
