Ethanol Roar

I have a 1996 Nissan Quest. Whenever I’ve used 10% Ethanol gas, I have a very loud noise that continues whenever the car is running until I’ve run through approximately two tanks of non-ethanol gas. I’ve located all the stations in the area that still sell non-ethanol gas. We’re down to only two remaining. I need to know what the problem is, and what I need to do to be able to use 10% ethanol fuel. Help!
