Answer
Hi Alex,
As stated in my "profile" I really know very little about the V-8 rear wheel drive Chrysler cars. From what you describe it sounds like there is something wrong with the fuel/air mixture control when the engine gets warm. I don't know how the feedback carburetor is controlled, but the one thing that comes to mind is the oxygen sensor which has a finite life and when it goes out that would result in an inability to provide the correct mixture. The spark control computer mounted on the air cleaner also has some control over the mixture, but I am not sure whether it does so with any inputs about the temp of the engine. I need to know more about what temp sensors are used to give you any other advice about that.
I also don't know about whether carb adjustments (idle mixture control) that might be available to you, but often these were fixed at the factory for reasons of pollution control and for 'foiling' amateur mechanics.
Whenever an engine stalls at idle the thought always comes to mind of their being a vacuum hose (one that is connected to the intake manifold, thus experiencing a vacuum) that has cracked or disconnected thus allowing air to leak into the manifold and dilute the mixture. So it is always useful to trace all the hoses having anything to do with the manifold to make sure that is not the case. There may be an EPA emission system sticker on the underside of the hood that shows all the relevant hoses to examine.
I think that is about all I can offer.
