Jeep Cherokee Stalls after idling for long

I have a 2007 Jeep Grand Cherokee Laredo limited 3.7l petrol with around 150k miles
I recently started have a problem where the car stalls after a long drive stuck in traffic

The car stalls when the engine is running without moving after an hour
During highway drives the car runs perfectly
In traffic the rpm of the car drop and becomes unsteady and car stalls
when the car is turned back on a noise of something hitting is heard
when taken to a mechanic they replaced the spark plugs and coils as they got a engine misfire error
I had replaced the starter Mortor a few months back and still sometimes it does not turn on and shows a “transmission over temperature” warning
the engine temperature reaches the halfway point when the problem starts

Hope someone can help me out

I just had this similar problem ended up being the black connector on the computer I had to cut it out and resplice a new one. Wiggle that connector while your car is running and if it does it could be it. I have a fix for it I can send you a pic of what I built if that ends up being your issue
