06 STX-12F 28HRS.Bought this week,ran good for 15min,then bogged down to an idle,would vibrate if you would try to throttle up,didnt shut down though,got back to trailer,restarted,run fine.Ran good the next day,missed one time,but quickly cleared up.No codes came on display.Worried about this,Lake Cumberland is big here in KY.Dont want to get stranded.Read all i can in the forum.Dealer said to change plugs,check for water in fuel,ECM could derate enging if a plug fouls or water in fuel,these issues would not log a code he said.Thanks,any help is thankful.Just joined the forum.:dunno::dunno:

I will post my findings,1&3 spark plugs were fouled,filled with 93 octane,replaced and gapped plugs,runs great.Has any one else seen plugs go out this soon.Dealer said four strokes are hard on plugs,as bad as 2 strokes.
