Sounds EXACTLY how mine acted when the fuel filter was clogged.
Can you ensure the lines are open and completely unrestricted? When you changed the filter, did the lines seem ok? Not collapsed or pinched anywhere? Maybe take the filter out and see how well fuel drains through the lines.
I agree with the others, maybe the pump. But I tend to lean toward a clog or restriction somewhere, especially with only 200 hours.
In any case, sounds like it's starving for fuel.
