Yamaha, 70HP 2-stroke (1997)

As soon as throttle goes above 50% it stalls out every time. It just started one day while on the water. There were no other signs of an issue. Still Runs great from idle to 50% and always restarts. In neutral you can rev the engine to the max and is sounds and runs fine. I am thinking some sensor is causing the cut-off. Any Ideas would be appreciated?
