Check the fuel pressure at the fuel rail just after turning the key to the run position. Is it within spec? Check fuel pressure with the car running also to see if it's within spec. If the fuel pressure is where it should be, you might have slightly leaky injectors that flood the cylinders after sitting a while. If the pressure is low, you might have a fuel line restriction or a bad fuel pressure regulator.

Also, pick up a bottle of fuel injector cleaner and run that through. I recommend a bottle of injector cleaner everytime you change your oil. It's amazing how many "problems" can be fixed and/or prevented with regular use of injector cleaner. They all seem to work well, regardless of brand or price.

It would also be worth monitoring the battery voltage while cranking. If it is dropping much below 10.8 volts while cranking, you might have a weak battery.
