150 Etec Power Loss

[champ]

I have a 2009 evinrude 150. This past weekend after idling thru the no wake zone I opened throttle and the engine just stopped dead, not stalled, but lost power almost like someone slammed on the brakes. I idled some more, then pushed the throttle and again the engine lost power. I idled some more and then gradually increased the throttle. A few minor quirks until I planed off, but then it ran fine the rest of the day.

Any thoughts?
