We have checked fuel pressure ,at 40 to 60 pounds. Is this the right range? We have changed fuel filter, spark plugs, checked distributor cap, and timing. Any suggestions as to why it may be stalling out and running rich?

    Fuel pressure sounds good. Have you checked for any trouble codes? Is the check engine light on?
