Hi, My 92 did the same thing until I found I had a small leak at the water pump. While running and under pressure it would push out fluid, turn off the car, pressure goes down no leak. But as the fluid would go down it would form an air pocket at the thermostat until it it got so hot the thermostat would open. Top off the over flow bottle and it would be fine for awhile. Till the water pump went completely. Hope this helps.
