2003 60hp four stroke mercury

Hi everyone, my engine ran fine for 20mins or so then while on the plane it started to alarm constantly, I backed off to an idle but still in forward gear with the alarm still on that’s when I noticed the engine wasn’t running on all cylinders, the moment I clicked it into neutral the alarm stoped & idled fine. I tried to putting it into gear again but the moment it moved off it started to alarm again & run rough, it’s like when it gets load on the engine it will alarm, sometimes I could slowly increase the throttle & could get back on the plane but it wouldn’t be long until it alarmed again.

Thanks for reading any help would be helpful, cheers
