Crusader 8.1 mpi surges at running speed
#1
2004 Tiara 3200 crusaders 8.1 mpi

While on my last cruise I was traveling at 3200 rpm and my port engine started to surge periodically.
Every so often it would surge to a few rpm more the go below and back to 3200.
Engine oil pressure and temps never faltered. Good the whole time.
At one point I increased throttle but the engine would not increase throttle.
Upon return to port I powered down to 1000 rpm for a few minutes.
Then brought her back up to 3800 to get on plane, and she responded normally.
Any thoughts on this?
Fuel filters were new this year and all routine maintenance has been done.
