NX4510 2016 tractor cranks right up idles fine then the gauges go to fluctuating and its like you shut off then catches right back up may run a hour then throws another fit is this possibly electrical failure?
I would check the battery, most importantly the battery terminals being clean, move on to the ground connections. also make sure your alternator connections are good. Sounds to me like you have the computer messing with the tractor, and most cases that is a connection issue and/or a battery failure, basically a voltage issue.
