Intermittent stalling L 6060 2022 random engine cutting out 10 minutes. 30 minutes 45 minutes. Any position starts out unable to start again usually not too much delay. I pulled the crossover two from tank to tank washed out. Both tanks with diesel. Fuel cleaner got no debris, checked it out with an endoscope so nothing is near, blew out fuel line coming to the water separator seems all clear water separator, clean new fuel filter. Not sure what the cause of could be any insights would be helpful.
