01 GTX-DI Wont Start ----Need Help!!

[dsym53]

I recently just purchased a used 2001 GTX-DI with 92 hours on it. I have taken it out a few times and it has ran perfect. It recently just turned over 100 hours and now the MAINT light flashes and the ski won't start. It turns over like it wants to start but it won't. Put in new spark plugs when i bought it so it can't be that. I checked some of the fuses that may be causing this and none are blown. What could be the problem here? Any help would be great!

Thanks
