Was driving my car to work today. Everything was going smooth until I went onto the on ramp (incline). All of a sudden my car started hesistating the whole way to work. It would not let me push the gas without it hesitating and stumbling. During lunch break right now I'm trying to start it and it will not stay running. It turns over runs for maybe 2-5 seconds and cuts off. I've replace the fuel pump, carburetor, points and the whole tune up. Also an inline glass filter was installed. It's showing gas in the filter so what could the problem possibly be? Please help and not just view.
