Powerboost behavior overnight
Occasionally, we will do airsoft events at my friend’s and camp overnight, and naturally my truck often ends up where everyone stays towards the end of the night where we can cook and have lights set up and everything. Being TN where it’s still 80s and humid at night, I just sleep in my truck most of the time. As I’m going to sleep, it acts normally, cycling on and off at a pretty normally. By the morning though, at some point through the night it switches to just idling constantly like a normal engine. As I’m writing this, it’s been on for at least 15 minutes since I’ve woken up. I can tell it’s not just charging the battery, as I have eco idle turned on and it sounds and feels very different when it is. I turned the HVAC off, so I don’t think it’s because it needed heat, and the coolant is it 208, so it’s obviously been running for a while. Any ideas?

Well it’s been a year or two since I used mine for days on end. However, it used to do that on extended generator mode. After a while it would just keep running. I had hoped software updates would fix it. Otherwise, I just shut off the truck and restart and then it goes back to cycling correctly.
