My 2015 50G is shutting down randomly but consistently. It only does it while hydraulics are in use. There is no change in RPM’s or perceived bogging of engine. It just shuts off in a similar manner as if it had a low oil safety switch like my Honda engine on my wood splitter. There are no codes on the display. Hours are 4795. All fluids are at proper levels. Engine temperature is fine. It had servicing and filters changed 95 hours ago. It has recently had the DPF deleted. It will shut down no matter how simple or complex the hydraulic usage is, wether for dual joystick maneuvers or just crawling. When it shuts down, you can lift the activation arm and immediately re-engage it and it cranks and starts immediately with typical engine sound and behavior as if nothing is wrong.
Also, it will run out an entire tank of fuel as long as there is no hydraulic load. It will shut down under hydraulic usage regardless of RPM setting or in or out of AI setting for throttle.
