I am starting to think you have a fuel line check valve problem. The fuel filter has the pressure regulator built in and when the one way valve is leaking it allows the pressurized fuel line to get air in it The fuel in the lines runs back into the tank and delay or even make difficult starting. That situation is not monitored by OBD so that would explain the lack of SES. If you can, stick a fuel pressure gauge on the fuel rail and let it sit overnight and see if the pressure holds.
