The most expensive and least effective way to diagnose any car is by throwing random parts at it. It will cost you less to have a mechanic diagnose the problem. In particular, other than diesel trucks, you'll never solve a stalling problem on a Chrysler product by replacing the fuel filter. The fuel pump will commonly fail while driving on GM products, but on Chryslers, they fail to start up. They rarely fail while driving. GM trucks have lots of fuel pressure regulator trouble too, but problems on Chryslers are unheard of.
The most common things that cause stalling when warm are the camshaft position sensor and the crankshaft position sensor. When they start to fail, they will work again after cooling down for about a half hour. When one of these sensors fails, the Engine Computer will not turn on the automatic shutdown relay. That removes power from the ignition coil(s), injectors, and fuel pump, through the fuel pump relay. There should be a diagnostic fault code stored in the computer indicating which sensor failed.
