I'm no genius, but I have a similar symptom on an '88 80.  Goes away after
a few minutes.  When I look into the engine compartment as it happens, it
seems to occur near the front of the car.  I suspect a water pump on the
gradual decline, and will get to it when I change the timing belt.  Water
pumps usually give lots of notice when they go bad, if I remember right.
Another possibility is a bearing on one of the other belt-driven accessories,
like the alternator or A/C.
