Hello! I've got a 1989 Ford L9000 dump truck with a Cat 3306B engine in it. While I was running up through the gears the other day, the engine just stopped pulling. It didn't quit outright, but wouldn't accelerate no matter the throttle position. I pulled over and parked, and the engine then slowly dropped below idle and died. I shut off the key switch, turned it back to run, and it fired right back up. No hesitation, ran great! It has done this a couple of times since, but always fires right up after stalling. I have changed both fuel filters, cleaned the fuel tank, and replaced the fuel pickup hose to the tank. I have a transfer pump on order, I have not checked delivery fuel pressure yet. The issue seems to happen at or above 3/4 throttle. Just strange how it will instantly fire back up. Any ideas? Thanks for any help!
