I have this same problem. It sounds terrible and it's very quick on start up which leads me to believe like most it's either the starter or the flex plate. Makes me cringe every time, though.

Starter or the starter relay. If it sounds like a grinder running down...that's the engine spinning the starter over. The starter gear is supposed to retract when the engine starts....if it doesnt, well figure your engine at what, 2K rpm upon startup with a gear ratio (assuming 153 to 12 tooth) of 12.75:1, thats 25,500 rpm. Yikes!

I also say starter relay as if its sticking somehow (also could be the PCM not detecting engine startup properly) then it may be keeping the starter engaged too long.
