RXP-X runs then quits

Will do that now, and post back thanks

Take Speedskixps advice.
Take out your ic, attach the water line to a water hose (don't turn it on all the way) while plugging the other end to see if it has sprung a leak. If it is leaking you will see water in the air passages where it shouldn't be! If it is, time to replace!
**If it is leaking, your manifold is probably full of water too. Be sure to drain it!!

Don't forget to wear your mouth guard

all u have to do is look for moisture in the IC tubes... if you have some then leaky IC but i have seen many skis run with leaky ICs with no issues except for loss in speed and RPMs, are there any check engine or lights on?

haha jackass!

Tested IC it is NOT leaking... ski is not throwing any codes either

Nope nothing... I am starting to lean electrical either another coil is bad, or fuel pump... unfort. I dont have another fuel pump to test out... do have extra coils I might toss in and run it again...

im thinking fuel pump is cutting out... or injectors, maybe someone has some stock x injectors they could loan you to try or a stock pump. im sure there are pleny of ppl with stock pumps on the shelf that upgraded the stock pumps

[JTAK101]

I am with you on fuel pump... if it was injectors it should do it at idle as well, but it idles fine... pulling fuel pump out now...

not necessarily true, these injectors get more voltage as RPMS go up i believe on the 255 X models... something could be messing them up...

[JTAK101]

I found some moisture on the MAP sensor, so cleaned it up, and going to test run it now, if that doesnt work going to disconnect the MAT sensor and see what that does, if neither of those work.. then going back to fuel pump... I see what your saying on the injectors... but just doesnt seem like an injector to me... Will post back after test run... Thanks everyone for the help so far...

I imagine you probably already checked this, but my X did the exact same thing one time, and it turned out the battery cable was loose. Just figured I'd throw that out there.

[JTAK101]

Well I am glad you did just throw that out there... As much as I hate to admit it, that was it... I never thought of looking there, since I never messed with that battery... Thanks man!

Thanks everyone else for the effort to, this forum sure comes in handy when you need it.

Awesome, glad you got it figured out and it was something that easy. Sucks you had to try so many other things first, but glad I was able to point you in the right direction.
