4iiii factory installed power meter - S-works Tarmac SL6

Wondering if anyone can help me troubleshoot the factory power meter on my SL6. This is the 3rd ride in a row where about 15-20km in, I basically lose all power. It just drops to 0, and the most movement I'll see is going up a hill probably putting out 500 watts, and the meter shows something like 20 or 30.

Taking the battery out mid-ride to reset and popping it back in doesn't fix it. Disconnecting and reconnecting to my head unit (Hammerhead Karoo 2, via Bluetooth) doesn't fix it either. But if the bike sits for the day and I take it out the next morning, it works fine for the first 15-20km.

Also, the left side stopped working long ago, and I've been riding with only the right side for a couple of years now.
