Not too familiar with Arctic Cat(know the old ones had Suzuki engines I believe),but have had some Polaris models do this also.It can be the starter switch as you mentioned sticking or a solenoid itself shorting out. If you can take the switch apart,I'd check it out first.Contacts may be touching.Don't know if these have a starter relay also that can short out?

 

I bought a new solenoid so it might be the switch let me check

 

So i replaced the switch and still wont start it turns but doesnt start

 

Then I'd ground out the plug to engine and see if you lost spark. Best to have a manual on trouble shooting electrical problems rather than throw any more parts at it. Here's a link to a free pdf manual I believe works.Toward the bottom is the down load button.2004 arctic cat 250 300 400 500 atv repair manual.pdf

 

i have the manual.. it started then when i gas it some gas it shut off

 

Have you tried fresh gas?
