Is your F150 an EcoBoost or the 5.0?
It is probably going into 'limp mode' when it does that. This reduces power, but keeps you moving and it won't necessarily steam or spit out coolant from the system, even running that hot.
To get the gauge to move, you usually have to have gotten it over 250* coolant temps.
If it's the Eco, you are likely using a lot of boost to maintain speed and while the power is there, the cooling isn't when it's over 10psi of boost.
Could also be the water pump. I think the OEM has plastic impeller in it and it could have broken some of the fins..
Only guessing here. I have to watch the boost level and temps when working my 13 Eco. I monitor with a ODB2 plug in and phone app. Gives me actual temps and the boost psi among a ton of other sensor temps and things..
Good luck! Mitch
