Oldsmobile/Buick Repair: 95 Buick PA (57000 miles) engine dies, heater fan, fan motor

Question
Previously described problem - engine cuts off when slowing or coasting. NEW INFORMATION: Yesterday I continued to experience this problem, BUT under these circumstances. When the heater was off: NO stalling or engine cut off. WHEN THE HEATER ( and fan ) WAS ON: THE ENGINE WOULD CUT OFF EVERY TIME I SLOWED OR COASTED. RPM HAND WOULD SWING WILDLY AND AS IT NEARED ZERO ENGINE WOULD DIE. I REPEATED THiS EXPERIMENT PROBABLY TWENTY TIMES AND THE SAME THING HAPPENED EVERY TIME : NO ENGINE CUT OFF OR WILD SWINGS IN RPM WITH HEATER OFF !!!! WITH HEATER ON - WILD SWINGS IN RPM AND ENGINE DIE EVERY TIME !!!!!.... Your input please. bob
