Alright guys, I have 99 200 optimax that it cutting out when getting on plane. Reeves up to 4000 rpm quickly and then stalls for a second or two before rpm increase. Also noticed a slightly rough idle. Just replaced all plugs and found a loose fuel line that I tightened up but it's still doing the same thing. Thought maybe a coil pac going out but I all seem to be fine to me. Any ideas?
