BF200 power loss at full throttle

[Jeff J]

New motor last year. 121 hours. Typical clogged fuel filter symptoms except both have been changed. Runs great for about 2 miles at full throttle then falls on it’s face. Let it idle for a bit then go again for a shorter distance. Primer bulb doesn’t collapse. Pumping primer bulb when engine loses power does nothing. I am having the boat trailered and brought to the shop to check fuel pressures (I can’t reach to make the connections on the water).

Is there anything else I should be looking at while it is on the trailer?

Thanks
