Brian,
You seem like the man with the education on these toys.
I have a question, maybe you can share some knowledge.

I have a 04 Mobius LSV with the 320 EFI.
Broke it in slow, 3k max RPM for first 4 hrs, 4k max for next 4 hrs. Typically on and off throttle a lot, let it completely cool often. Felt like I did it right.
At 8 hrs starting pulling behind it, runs like a champ. Using Perfect Pass when pulling.

Starting heading back to the dock this weekend rough water, afternoon, 1/2 tank of gas still in it. Boat started surging and Perfect Pass while turned off would beep each time the boat surged. I stopped, went to neutral, made sure P.P was off, it was. Took off again and it started doing it again.

Next day same thing, when water gets rough and boat bounces around a bit at about 3k to 4k it surges and P.P beeps at me. I called the dealer and asked what I was doing wrong, he is going to get back to me with some tech support.
It feels like the boat is missing or running out of gas and it is weird because the boat runs like a champ all day until the water gets real choppy. Very odd.
