    This may be a fuel pressure issue. When you turn off the engine after it is warm, it is important that pressure remains in the fuel system to prevent the fuel in the lines/injectors from vaporizing. So check the fuel pressure with a warm engine, and when you turn off the engine fuel pressure should remain in the system. If the pressure drops, then you have a bad injector (leaking) or a bad fuel pressure check valve in the.
