Way would car stop when runing
Any number of things. The question is too general to even get into coming up with a guess/solution. Let try again, any lights on the dash, how is it running otherwise, mileage, last time you tuned it up, other symptoms, etc.
Try some starting fluid to see if your car has a fuel delivery problem.
I agree with the first response. But do the vehicle idle okay or does it shut down doing acceleration? Please provide any additional information that may help.
