Weird Random Reving issue

[RMcElarney]

Alright '04 RXP. If I toss it around a lot it will randomly just begin to "buck" By this I mean it will essentially drop down to an idle and no matter what if I to WOT it will just to a Thump Thump Thump and the revs won't raise at all. Obviously because of this I settle the ski down in the water and a couple of seconds later go WOT and she jumps right back out of the water full power. Anyone explain what this is and why it happens?

I remember it happening one day with low fuel, so I figured it was a fuel starvation issue, but then another day it did it with a significant amount of fuel. Is this the TOPS kicking in? Is it oil starvation?

Thats your TOPS system coming into play. Unfortunately its perfectly normal for the stock ECU machines.

Alright so is it kicking in because of just solely angle of the ski, or does it look at some other aspects?
