The vehicle has 3.9 magnum motor in it. I have recently replaced the following:

Exhaust from cat to tailpipe, Rust repair and body work (not relevant), Upstream and downstream o2 sensors, High voltage o2 sensor circuit repair (wiring), Fuel pump and in tank filter, Oil change and filter, Map sensor, Ignition coil, Distributor cap, rotor, and pickup coil.

The issue I’m having is that after the vehicle gets hot it stalls, has a hard time starting again, runs poorly and idles rough until it cools down again. Once it cools for a bit (like 5 to 10 minutes) it runs okay until it gets fully hot again. Alternatively if it’s fully cooled down it runs perfectly.

There are no codes/no check engine light.

I’m leaning towards possibly vapor lock or maybe a purge valve or charcoal canister but am looking for advice and input. Thanks for reading.
