warm start problem

my '88 190E w/ 230K cold starts and runs great with normal fuel consumption. however, if, after driving for a while, with temp in normal range, i shut the engine off and immediately try to restart, it cranks fine but won't start. after 3-4 mins of off time, it starts right up and runs normally. the symptoms are quite consistant over the last month or so.

all ideas welcome.
