I have a 250 sawtooth, after awile it just quits running and will not start again. any ideas

 

they made a 250 sawtooth?

i thought it was a 200? or a 300?

...the hawkeye was the 300 right?

 

i have a sawtooth 200 and i am having the same problem. the unit runs well for about an hour then cuts out and will only start if i pump the gas and put the choke on then it will die shortly after that and not start up again. it starts back up about an hour after it died.
any help would be great!

thanks...
