I have a 1995 Chevy Beretta and it has the 3.1 in it. I can drive the vehicle when its cool outside all I want but once it gets about 70-80 degrees outside I have the worse car ever. The fuel pump will start making a whining noise (which I already changed thinking that was the issue) then about 15 minutes of riding the car will just DIE out and we have to sit on the side of the road and just let it cool down so that we can start it again and be able to ride about a mile or so before it does it again. Any help is much needed right now. Thanks.
