Have you considered the radiator may be blocked up in the bottom part reducing cooling capacity?
The sensor signals the PCM to reacts that way to save the motor.
In colder weather is may go away for awhile then return as the temps get warmer.
Overheating to many times in these motors is a no no.
Good luck.

We'll the funny thing is when it does it you turn the truck off and start it right back up and it runs fine back to normal so I didn't and the radiator is no warmer than when it is running normal
