Sounds like it's time to check some stuff. Check the PCM connections as been stated before, I don't know about Mopar but on Fords you MUST have the battery disconnected if you disconnect the PCM.
Other than that, I'd do plugs, wires and coils. Definetly something with ignition acting up on rare occasions.
Not a misfire. It pulls strong, I've got no problem whatsoever. Just a random BIG bang while decelerating at high speed once every 1,000 miles or so. I never changed the spark plugs since I bought the car in 2017 so yes I think it could be a good idea!
