If it's an overheating issue, this can be caused by the type of SD card that you're using. A card that is too slow to capture 5.2K (or 5.6K if you're using the latest beta firmware) will be prone to overheating. Ideally your GoPro should not feel "Warm" at all.
I had overheating issues when filming with a GP4 Black mounted in my window, I often found the solution was to lower the car heat and turn on the front window demister (this turns on the a/c and directs the cold air directly at the window thus cooling the camera).
I can understand your frustration with GoPro's website not giving the complete specs regarding their camera's on their website. For me the dual memory card requirement wasn't an issue as just about every camera review website mentioned this, I also have a lot of spare SD cards due to my constant filming with my GP4's and GP6's. However I do believe this could have been mentioned on their website more prominantly.
I also use one of my Fusions as a dashcam (I have another one mounted on the roof of my car) and I've had my footage featured on the local news a couple of times. I have also recorded anywhere from 12 minutes to 1 hr 30 minutes at time without any overheat problems. However like I said, I do tend to keep my camera's cool (the outside camera has constant airflow over it). They camera's all use the same brand 128GB SD card's and I haven't experienced any issues with them. I would make sure using a good SD card as recommended by GoPro and if you still have problems, try manually updating your camera or updating to the Beta 2.0 firmware.
