Check the fuel pump and the fuel filter. Sounds like a classic fuel delivery issue to me ----------

That starts to sound like and ignition failure and unburned fuel ----------- Maybe somebody that knows your model better than I do will come along with some help.

Possible ignition coil or component failure after operating temperature is reached. Have used a heat gun (industrial/military strength hair dryer) to induce temperature related component failures in my past life.

One thing at a time ---- make sure that the fuel pump/fuel filter are healthy before you do anything else.

 

[RetiredCarGuy]

A fuel supply or quality issue would exhibit itself right after starting. The complaint here is only when operating temperature of all components has been reached.

Dumping fuel first is reccomended and fundamental.
