Not necessarily all of them. Plenty of stuff will drop out while cranking; hopefully not the computers that run the fuel injection and ignition, though.

Interesting. I now know why my windshield wipers quit for a sec when my vw auto stop/start kicks back on.

		Not a car engineer, but those motors can be pretty high A, so this could also just be a feature that helps the starter get as much power as it can while cranking.
