Superjet bogs but only with trim pulled

My 760 runs great with no bogging at all but when I pull the trim it bogs and if I don’t let off the trim to get it running smooth again it will bog so bad It dies. Any help is much appreciated!
 
are you riding around doing wheelies with the trim pulled? If so you could be sucking exhaust into the pump causing it to cavitate. Otherwise, Pulling trim is not going to cause the motor to bog.
No I am going and bumping the throttle to get the nose up and then when I hit the wave I pull the throttle and the trim and it bogs out

It runs fine if you leave the trim alone under load? What about cranking the bars left or right?

These are seperate systems. Output of motor feeds input of pump.
 
This is really odd. If it truly only happens with trim, I would look for flex, under load, in the cable messing with the motor somehow. Maybe grounding the ignition?
