Ok I’m going to try to explain. My 2016 pioneer 1000 will run great for a couple hours and then shut down. It will down shift threw the gears and then shut off. Start back up and run a little bit then die again. I had this problem with the injector wires a few years ago. I checked those and they are all good. Put a fresh battery in and it’s still doing it. Drove today for a couple hours fine then started acting up.
