A ruptured diaphram caused the leaking fuel which in turn caused the engine driven pump to cavitat and loose fuel pressure. The lack of fuel pressure caused the engine to auto shutdown. The download of the flight data recorder confirmed the fact that a lose of fuel pressure occurred. The engine and pressure switch were removed and replaced. The engine, because of a sudden increase in itt. (992.5). The valve is manufactured by hydro electric.
