I have had my LLY start and die shortly several times, has always been air in filter assy and high pressure system. Have always been able to bleed, rather hand prime pump the filter assy, all ok. Usually in spring and usually after hard pull or long run shut off, then restart and die. I also have a CAT prefilter that I believe helps seperate the air from fuel, added low pressure transfer pump to eliminate problem. May be a stretch to be same prob as yours but,, no codes , could not find anything???, may have been air and was just hard to get primed through system. bob...................
