2002 200 vmax cutting out , does it every time if you drop the hammer (wide open throttle) to get on pad , will get just about to break over and it cuts out like it starves out on gas, if you back off the throttle you can catch it and get back after it and will run fine, Once your out and running you can run wide open for miles with no problems, Also if you just ease it up on pad say 1/2 to 3/4 throttle it doesn't seem to bother either. I've changed out the fuel and put in fresh, checked primer bulb and its firm, I'm thinking maybe lift pump diaphrams? if so are they expensive and or hard to change out? If anyone has experienced this please let me know!

Thanks
