Any codes or anything? Have you done any diagnostics? Any strange or new sounds like knocking or whooshing?

You just had new plugs installed, was this because of the misfire, and dying at temp? What misfire codes do you have? It would be worth pulling the plugs and coils on those cylinders and doing a visual inspection. It also wouldn't surprise me if someone damaged a coil twisting and pulling it to remove it.

I want to lean towards something in the ignition. When coils start to go bad the expansion from the engine heat can cause them to foul. What cylinders is it giving you the misfire for?

Change the coils to different cylinders and see if the error follows the coilpacka
