Engine RPM drop when running about 3300

[Surreel KD]

Just looking for some guidance regarding a problem with my starboard inboard engine. Overall, both engines are running fine (oil, temp, volts) all look good. After about 30 min of running or so (at about 3200 rpm) my starboard engine rpms will start to drop as if it were starving for gas. Eventually the engine recovers if i let it run or back off on the speed a bit but it is a bit concerning. Originally we thought it was a fuel problem but it appears to be coil related. The engines are Volvo Penta 5.8s with about 200 hrs. Does anyone have any experience with this?

Thanks

Ayuh,... It probably Is,.... Did you pull the Fuel Filters,+ Inspect the contents,..??

I seriously Doubt it's a Coil problem,... They usually just Die...
