Changed fuel pump, fuel filter, fuel pressure sensor and sent fuel control module out for repair. Still after idle down car start to stall then die. Restart every time but eventually idle down and die. Can hear pump kick in and idle up but eventually kill.

Sure it's fuel and not coolant temp sensor? Checked fuel system pressure? Had bad temp sensor on my truck and temp sensor was causing the computer to flood the engine. Would idle down, then low, then died, exact same behavior.
