I had similar problem with my 2.5 Alfa 90. She was starting cold and runing a couple of minutes. Then the idle was disappearing and the engine stop. If I tryed the engine was starting again but without idle. I changed a lot of things but there was no effect. Finally i have found that the connector in red circle was loosen. My opinion is that your car sucks air from somewhere - some hose, the gasket of the throttle body or even the servo...
