What is wrong with my 1998 monte carlo?

Sometimes my car won't start and other times it does. When it doesn't start it makes a chugging noise. A couple of times it just shut off while I was driving; it also shuts off when idling. I replaced the fuel pump amd replaced all the filters, plugs and hoses. Any ideas?

    Please give a better description of a chugging noise. You should perform a compression test.

    Edit:

    Since you removed the catalytic converter, the Check Engine Light must be on unless you somehow bypassed that. Have you checked the air filter? Have you checked how much pressure you have at the exhaust pipe in case the exhuast system is plugged up. You could try taking it to an auto parts store and have them scan the vehicle for trouble codes. They do it for free.
