Car starts then dies after a couple of minutes

Hey guys, I need a little help with my da. I searched but found threads that dont say what fixed the problem.

My car starts and bogs in first and second but on the highway it is fine. It sometimes has a hard start, but when it starts it smells like it just burned a lot of gas. After a little while it smells regular, but then the car will idle low and then sometimes die. When I step on the gas it sometimes wants to die even more, like it is running rich.

Upon my searching I found that a clogged catalytic converter would cause this so I took it off to check it out. The cat was clogged but the car still does the same thing.

Any suggestions.

Thanks
