Sudden power loss and running hotter...where to start?

2006 PSD CC 4wd, 134k.

Generally my truck runs cool if anything. Mid 60's low 70's temp in my area. Usually my ECT is 186-188 or so with EOT in the 196-200. When it does get hotter say ECT 196 or so the ECT will never be more than 7-10 degrees higher.

Yesterday driving home from work, 62 degrees. Just cruising the ECT is 198-204 and EOT 212-218. At one point it did go a a delta of 15 degrees very briefly.

It was almost as though the truck was not shifting into overdrive. I noticed the boost gauge was higher than normal even though my foot wasn't in it at all. In fact I backed down to like 60mph and watched my Scan Gauge closely. I pretty much babied it home.

I'm aware of the EGR/ Oil cooler issues, but I've been watching the ECT/EOT closely and have never seen a delta that would cause concern.

Could it be something else? There were no codes thrown.

Where should I start?

Is the thermostat OEM or from the local parts store?

To my knowledge it is OEM. As far as I know everything on the truck is.
