This could be carbon fouled CIS injectors leaking fuel after a hot shutdown until the accumulator spring loaded diaphram is back to it's relaxed state and flooding the motor in the process.
The hot start symptoms are exactly what you are experiencing.

[I posted this the other night but my post was deleleted during all the server timeouts and later the database transfer to the backup server]

All CIS injectors will eventually do this because they stay open continuously while the engine is running.
Electronic injectors do not do this because they are constantly opening and closing and because of this they are self cleaning.

A can of techron or seafoam may help, but usually they have to be removed and cleaned to be succesful.
