Could be fuel fouled plugs from excessive cranking which cleared after idling for awhile.

Initial hard start might be the cps if the tach was not bouncing during cranking.

Could also be the first sign of a failing fuel pump or relay.

Regardless, as it has been said before Porsches will get even for letting them sit.
