1998 yamaha 225 xo66 2 stroke outboard

by Kenneth

When I blast off in the morning, the boat gets on plane with no issue. As soon as it planes out it dies. I can pat the peddle and it will pick back up then die again. After running it for 30 minutes or so this go's away.
I have changed the fuel pumps (the main pump and the 3 on the side of the motor). I have cleaned or replaced all fuel filters even the small one in the regulator. I have changed the 02 sensor 3 times. I replaced all hoses from the tanks to the motor. Replaced the VST filter. Changed the water separator. I just can't fix it.
Any ideas?
