I have a 92 Suzuki quadrunner 4WD that starts and runs great, until it is warmed up. Then it dies and won't start until it cools down. I am looking for some ideas on what the problem could be. I don't know if it's carburetor or electrical.
Thanks for your help

 

most likely you are chokeing it to warm up? your pilot/slow jet is clogged and your unknowingly using the chke as the idol circit, so when its warn you turn off the choke and it dies. a good carb cleaning wont hurt anything and can eliminate that problem

good luck

 

the reason why it wont run when its warmed up is because u have to ride with the choke on for a while then turn it off

TRUST ME i had too with mine

 

I agree that the carb should be cleaned. Always a good place to start.
If the problem persists, I'd be checking the CDI. Hot/cold is usually electrical.

 

Take The carb out drain it and clean the carb then put it back in

check your spark plugs

change your oil and everything in the engine
