Misfire when ac is running. P 0339 and 1618 code

I have a 2012 jku sahara 3.6 engine, automatic transmission.. been having the same issues for the past two summers which is when I put on the ac and drive for a while my check engine light comes on, then the traction control light, and then a red lightning bolt starts flashing, engine starts shaking, and running rough and the Jeep shuts down. I can smell burnt fuel or whatever also when this happens. Once I restart the vehicle and drive without the ac it’s fine. Check engine light goes away. I’ve noticed that right before this happens, my outside temperature gage that is displayed on the dash will start rising in temperature, the radiator also starts getting really loud like a jet is about to take off. I’ve changed the spark plugs last year which solved the problem for a short time and I’ve changed the crank shaft position sensor 3 times in 6 months and recently bought a new battery. If anyone has any solution to what may be causing this please give me some advice. Thank you
