Answer
Don,

Check the fuel pressure.  I bet one of the fuel injectors is leaking down after you shut off the engine and it is flooding.  So, it has to sit and wait until the gas evaporates.  The easy way to find which injector is to take the plugs out, one at a time, and see which one is really black.  The darkest one is where the leaking injector is.
