Dying car

Now we have a new problem with the 1995. When the car is cold it runs alright but when it warms up it idles rough and dies on us. It has new plugs, fuel filter, fuel pump regulator, fuel pump. The motor was just rebuilt, we had the problem before and still have it after the rebuild. There is also a strong smell of gas in the cab.
Any suggestions
Thanks
Rick
