Motor runs fine at idle and in gear. when i cruise at full throttle for 35-45 minutes rpm drops from 5000 rpm to 3000 rpm and feels like cylinder misfiring, will not throttle up pass 3000.Turn off motor let sit for 30 minutes or so runs fine after 35-40 minutes sometimes sooner it happens again drops to 3000 rpm. I replaced fuel pump, fuel filter, coils, spark plugs, rebuild carburetors
