Where does fluster come from?

The verb is probably from Middle English *flostren (implied in flostring, flostrynge (“agitation; blustering”)) from a Scandinavian (North Germanic) language; compare Icelandic flaustra (“to bustle”), flaustr (“a bustle; a hurry”). Compare Old English flustrian (“to weave, plait, braid”). The noun is derived from the verb.
