The other day while running do

The other day while running down the lake at about half throttle my motor (efi) starting missing/cutting out. I trimmed up and held it on the floor and it cut out a little then cleared up and ran like it was supposed to. After stopping and fishing for a while I went to move again and it would barely get on plane then it wouldn't turn up like normal. It will only run about 5000rpms or feels like about 75%. I just put a new set of plugs in it but that wasn't my problem. Someone suggested a coil may be going bad? Any help would be appreciated!
 
you can put a timing light on

you can put a timing light on each plug wire while on the hose or lake to see if that cyl is getting spark. After that someone with more knowledge will have to help.
