I posted this already in the newgroup and got a reply from SBT to which I acted upon and oredered the fuel pump kit. Wheter or not this solves my problem I think it's a good idea to install it.
I've now received a response from another fellow who doesn't think this is my problem. Here is the thread and attached is a picture of my fuel pickup cap on gas tank...could this be a problem? It is cracked all around....I repaired it temporarily with liquid gasket but haven't tried it yet.
Any ideas would help...
Thanks,
Vince

I don't disagree with SBT on the undersizing of the fuel pump but don't
believe that is your immediate problem. The fuel pump issue causes
long term problems, not sudden changes in operating performance.
However, there is also another problem with the fuel pump called an
auto cock which was a vacuum controlled fuel shutoff valve. They all
failed - there was a TSB to the dealers years ago about the problem and
how to bypass the feature. Bypassing it leaves you with no fuel cutoff
option but should clear up the problem you're discussing. The other
possible issue is the sealing around the throat of the pickup tube
itself. They can develop an air leak and can't continue to flow
sufficient fuel and so the ski leans out and starts to die. The choke
creates more pull on the fuel, thus the reason it runs with the choke
out. Honestly, that ski was on of the early efforts by Polaris and had
several issues associated with it so I wouldn't sink a lot of money
into repairing it.
