Engine shut off at 3000 RPM's...

[Katemma Life]

Back story:
Replaced my gen III cool fuel module completely this winter
Slight bottoming out yesterday - may have sucked up sediment into the engines

Today, engines started fine / ran fine out of the inlet at 1000 RPM. Got to open water and throttled up to 3000; port engine just shut off. No smart craft alarm or anything. It wont start back up. Starter motor turns the engine over but wont fire. Cant see any leaking.
F'ing frustrating! Anyway.. anyone got some ideas? I believe the new Fuel module had new fule pump in it.
I have run the engines hard up to 4200 rpms without issue just last week.
Thanks if you have some ideas or direction..

CHeck fuel pressure and check for spark.
Let us know what you find.......or Don’t find.

mechanic pulled plugs. was a hissing sounds. plugs show evidence of water infiltration. Compression in cylinders is good however.
more diagnosis needed I guess. seems like an internal leak. great way to start the season
