Have you checked the screen filter/strainer on the pickup in the tank? (If it has one)

-I ask because one of my trucks did this, would run around the block OK, but would surge and die as fuel demand increased under constant load. It was pretty confusing, because by the time you got out and looked at the see-through filter it had time to pull enough fuel to fill it back up. I finally caught it and realized what it was. I pulled off in a good spot, pulled the sender/pickup out: and oh my God, the horror! Totally plugged with rust. Couldn't even see the mesh anymore. Cleaned it up with a wire brush and was back on the road in a few minutes like nothing had happened.
