I have twin 2007 suzuki DF 60's running a 19ft glasspro. The port engine runs all day at 2300 rpm but the last two times out the engine intermittently drops to idle when I throttle to 3,000 rpm or above. If left with the throttled up, the engine comes back up to speed a few seconds later and then bounces back and forth between idle and the intended rpm. I have used two independent fuel sources and fuel separators now and believe I can eliminate fuel quality. Do anyone have advice or suggestions?
