Mine would do that is I moved it off the drive to let somebody out and yes it could be a difficult to restart sometimes, a new set of Iridium spark plugs and a set of MSD ignition coils seems to have fixed it.

If a car is difficult to start with modern EFI there is usually a problem, the usual culprits are a weak spark, dribbly injector or injectors, air leak or in some cases a poor starting technique. A lot of people don't know but flooring the throttle when you try to start a fuel injected car often switches the injectors off, this is so you can clear a flooded engine.
