So just about an hour ago i went to start my car, it ran for a good 45 seconds then shut off...then didnt want to turn on again. Then i got it to run for about 30 seconds with the choke engaged, but as soon as i put the choke in it shut off...I don't know what it could be. Any help would be appreciated

 

update. it ran for 60 seconds with the choke before shutting off... i think it could be the spark plug wires.

 

i thought it was the spark plug wires too....you know what it was...i havent checked my air filter in quite a while. took off the top and it ran fine.
