I have a 2002 jd 260 2 speed and it died on me the other day after a full day of use the day before. I could get it started but would die as soon as any pressure was put on the system. I changed the in-line fuel filter and drained the water sep. It started but would die between 10-120 secs. I then changed the water sep. and the air filter, nothing. Used stater fluid and it cranked, ran for a copuple minutes at half throt and died. it doesnt sputter it just dies like theres air in the lines. Started it again and it ran for 30 minutes under a decent load moving some dirt. Then it died again. I changed the fuel pump and still nothing. Is there anything else to check before i change the injector pump?
