Intermittent spark on #1 cylinder

Just a general question. When my motor sits up for a week or more and I start it back up cylinder 1 isn’t firing. This last time i got my meter out and realized I had no trigger voltage into the ECM for #1. I had a spark tester on the #1 and no spark, then all of a sudden without me doing anything #1 started firing ok and I now had a trigger voltage on my meter. I took boat out and it ran fine all day but if I let it sit for a week I will have this same issue. Has anyone had an issue with an intermittent trigger like this. The wiring from the trigger looks good so I suspect the trigger coil but wanted some ■■■■■■■■ from you guys. Hopefully Chris or Loopervet will respond
Thanks


I WOULD LOOK FOR CORROSION IN THE WIRING !!!
