Common kind of problem in Pathfinders, but many things it could be in emissions, sensors, etc.
If you suspect a heating issue and not sure , if you have a infrared heat gun I would warm it up to operating temps and shoot it with the temp gun to get an idea.
Did you check the codes to see if it is giving a code ? I know if you do not have a good service manual and lots of patience, you can spend a lot of time time chasing your tail on them !
Process of elimination parts buying can get pricey !
The temp gauges or not so dependable in these like the gas gauge is not, so I would start by knowing if it is heat related and go from there.
