There was plenty of fuel in the car every time it happened.

I replaced the air filter today and found that the old was really dirty,
I went for a 5 hr drive tonight and it is definitely still happening.

I was pulling a small trailer with nothing in it and it usually drove fine, but sometimes it decided that it wasn't going to go faster than 90 and the exhaust temp started to go up.
I didn't let it get over 400 degrees.
