NW MN | I would also say check your fuel pressure. Does it matter if the fuel tank is full or close to empty? We had this on our 835B with 3000 hours on it. Our fuel pressure was really variable and would get fairly low under load for a few seconds ( 40-50 psi). After throwing a bunch of money into it, finally found that the outlet screen in the tank was plugged with plastic shavings. It would lose power randomly and finally got so bad that the engine would cut out. This always happen under load, never when it was idling, which is different from yours. But it might be worth a look. | |
