I had this happen with my KB. The bottom of the intake manifold contacts the top of the cylinder head temp sensor. The wire gets pinched, the car thinks it's overheating, goes into limp mode and your screwed.
Two solutions:
Order new and different sensor, trim the top plastic so it doesn't contact. Problem solved.
Trim the sensor you have, repair wire.
I replaced the old one with complete new wire and sensor as the broken wire was nearly impossible to fix and be sure it was fixed correctly due to it being to close to the plastic.
The sensor is located in the front left side of the valley under the manifold.

One question though, would this problem cause my coolant temp gauge to stop working? Or is that something else?
When my car is warm, the temp gauge will work for a few seconds, but then just quit.

Don't know about that.
The gauges do have defaults they go to based on historical readings. Not exactly sure how it works, but the sensor will need to be fixed before you can really diagnose the gauge.
