I have a 1991 Mizibitzi Mirage that runs fine for about 1/2 hour then starts to sputter as though it does not get gas or gas line plugged up. When it starts to sputter I really have to give it the gas to keep it going. I have changed gas lines, fuel filter, spark plugs and distributor cap. This is still a problem at all speeds, and in all weather situations. What could be the cause? Failing fuel pump? failing oxygen sensor? Help.

Off the top of my head, this sounds like vapor lock. Try driving it around without a gas cap on it and see if it doesn’t change.
It most certainly could be a fuel pump. You should test fuel pressure when it is running good and then check it again when it is running bad.
Have you any check engine light codes?
