The engine will lose power, not shut down, but just drop back to idle intermittently after about 10 minutes on plane. It can be powered back up and may or may not have the problem the rest of the day. My fishing partner, the boats owner, seems to think it helps to trim the engine up then back down to resolve the problem. This weekend on one day, the problem occurred about 10 times within a 20 minute period in the am and then only once all pm. On the second day, it did it only twice all day. There does not seem to be connection to a specific speed or rpm although it did happen almost at the same place down the river on both days. The am/pm connection may not be significant as in the past, the problem was just as bad in the hot pm as in the cold am. Other than this really annoyance intermittently, engine runs well. <br /><br />Local mechanic has replaced computer, tested fuel pressure and replaced kill switch to no avail. Installation of a water separator has been thrown around by buddies. Any thoughts on the possible problem and solution?
