[steplift20]

Ok this is my problem today, I went out with my 1978 Steplift she has a 1988 150 Mercury blackmax , she was running great then she lost power for a split second but kept going, then it happened again it felt like it was bogged down but only for a split second, we drifted awhile and when we started her she started and stalled when it went in gear, she did that a couple of times, then she would not start, we got her going but she felt like it was missing and only running on three plugs, it would be normal than bog down ,no power but we got back to the ramp , what do you guys think? And what should I check? I have a idea but want to hear what you think . Thanks for any feedback p.s. The fishing sucked in sandy hook today
