Bill your car has hardning of he arteries. Your problem is either the slave cylinder is sticking-the master cyl. is sticking- or the most likely candidate is the flex line (located lower left rear side of engine block just below rear exhaust manifold has collapsed. The pressure from your foot is pushing past the restriction but the return is not as strong so it bleeds down to engagement. You did not say what prep you made prior to this but the fact it pumped up arter 20 years is some sort of record for any car.
