Angry Coolant temp sensor...

This issue keeps coming back, and causing my car to lose significant power without triggering a CEL. When it happens, the radiator fan kicks in high blast, I lose power, the oil temps drop really fast, and I have to pull over and restart the car. When I restart the car the rpm kicks in and maintains 1000 solid at idle for about 20 seconds, then it starts to come back down to a normal 6-700. This issue happens to me both with and without my procede rev 2.5 installed.

I've looked at other threads regarding this issue, and it seems no one has really come up with a solution or knows exactly what is going on, so I'm starting this one to get some fresh input on the subject as I know there are some people out there still experiencing this same problem.

Would the best thing to do be go to the dealership and have them replace the sensor? From what I've been reading, it has nothing to do with the sensor itself..
