Car starts and then turns itself off if I don't give it gas

First try adding some seafoam fuel injector cleaner to gas tank if that does not help replace fuel filter.

The cold weather and humidity make the idle air control valve stick on fords a lot of the time. It's easy, pop the hood and look at the top of the intake where the big rubber air tube goes to it as you would expect the air to flow into the engine past the throttle body there is the iac valve (cylindrical with a 2 wire connector). use a 5/16 or 8mm socket to remove it and spray the valve part of it clean with carb or brake cleaner. reinstall and try her out. If that isn't it then you can cuss me for the 5 seconds it took to clean it for free. It's Friday and getting weird here at work.
