Car Puttering Until SES light comes on
 

hey guys
i just got my car back
car drove fine for like 20-25 minutes and then at highway speeds it started puttering and acting up
it just had a lack of power and didn't want to drove smooth
until the SES came on and it drove fine
SES only stayed on for about 5 minutes and went off
as soon as the SES lght went off, the car started puttering again
i luckily got the car home
any ideas?
thanks
