I have a 2019 bighorn, (6lug pattern) truck. It randomly starts, at first I thought it was the key fob. When it sits for a while and it’s cool out it starts and I can drive it, but after all day I go to drive and it won’t start, the dashboard gives all kinds of errors when it does this. I have run codes on it and nothing shows up. Disconnected the battery (new battery) wait and after min of 20 mins it will start. But it keeps leaving me stranded. I replaced the fuse box under the hood, that worked for couple of days. Makes me think something is getting to hot. Not sure what to do next. Does anyone have any suggestions? Thanks
