I don't know what the cause is, but it sounds exactly like what has
started happening in my '91 after it's warmed up, then I stop somewhere
for a short time (15 - 30 minutes).
It's almost like the ECU is not handling the "warm but not fully warm"
condition properly. In the summer I was having a much more serious case
of these symptoms (i.e. the low power/hesitation/stalling would last
more than just a few seconds). I replaced my "Temp II" sensor which
seemed to completely cure the problem, but now it seems to be returning
or something else with similar symptoms is going on.
