    Ski cutting out and losing power

    I just bought my first ski and when I took it out it was cutting out when riding it. It would also not allow me to get going more than about 35 mph at some times. Any help would be greatly appreciated. It is a 2001 Polaris Virage TXi.

    Welcome

    We will need some more info.

    What is the service history on this machine?

    How long have you owned it?

    Has it ever run properly for you?

    What checks and diagnostics have you done so far?

    Thank you for the welcome, I have only had it for a week. The guy I got it from said the motor had some work done to it just before he got it and he had it for just four months. Is there any thing I should check to make sure it is in proper running condition?

    Sounds like this machine has had a chain of owners, and you don't know what has been messed with along the way.

    My suggestion is you need to check almost everything.

    Do you have any idea what was worked on previously?
    Any signs of repairs?

    Check cylinder compression (plugs out, throttle wide open).

    With the engine running, the fuel pressure (should be over 20PSI), and injector voltage on the White/Red wires (with all injectors plugged in) should be around 45 volts DC.

    Ohm check the spark plug wires, and make sure the correct PZFR6H spark plugs are installed.

    Has it ever run properly for you?
    (full RPM should be around 6700, sustained)

    Do you have access to another TPS (Throttle Position Sensor)?

    A bad TPS can cause strange running problems. If the other checks seem good, you may need to replace the TPS sensor, as they can not be reliably bench tested.

    Thank you for the help. I will check out all of those things.

    What do you mean by 'cutting out'?

    Does the engine stop running, or run roughly?

    Does it restart right away?

    Any red lamp or warning message on the display?

    It doesn't die unless you let off the throttle, but when you go to start it it'll start back up. It doesn't really run rough but it wasn't always reaching it top speed. There were no red warning lights coming on.
