Stalls when I start it on cold days, must restart at least 15 times. Crankshaft sensor has been replaced plus complete tune up. Sounds like a choke problem from the fifties. Once it warms up it runs great.

Check the ECT(engine coolant temp sensor) It acts like a choke for fuel injected cars.
Engine Coolant Temperature (ECT) Sensor If a coolant sensor-related diagnostic trouble code is present, see TESTS W/CODES - 3.1L article in this section below. An out-of-calibration sensor may not set a diagnostic trouble code. Use following procedure to test sensor calibration. Disconnect ECT sensor connector. Measure resistance between sensor terminals. Resistance should be high when engine is cold and drop as engine warms. See ECT SENSOR RESISTANCE VALUES table.
