Compression?

fuel in filter?

Are you using your stock pipe ?? if yes do you get one of your 2 plugs wet with a milkish foam when this happens ??

If thats yes for both questions your oem exhaust chamber has a internal leak and water is returning to one of the cylindrs when you stop the engine,thats what happend to b1 and I had a real hard time getting rid of that missfire.

Good luck hope you get in the water again soon.
