How do you fix this 1997 Chevrolet Silverado starts up fine in warm weather now in cold weather acts like it's out of gas in mornings until the weather warms up during the day?

You most likely have water or water vapor in you fuel lines, try adding one of the moisture removing products available at your local auto parts stores to your fuel tank during warmer time of day to remove moisture from the fuel system. In cold (below freezing) temperatures the water freezes and blocks fuel flow.
