Since my last message, it appears that the fuel pump relay is not the problem. The car will run without the relay if I jump the contacts for the relay connections. The problem continues when the engine is warmed up and I release the accelerator at a stop. The engine dies and I suspect that the problem is related to the idle circuit somewhere. The idle control valve is receiving voltage and is functioning as intended. Perhaps the problem is with the throttle plate position sensor or the idle speed control brain box. Any ideas??
