The fuel regulator is icing over. I verified that there is water flowing thru. Before I start pulling parts off, I'm hoping somebody here will have the answer. I thinking may the diaphram is not working correctly. It runs starts and runs fine, but afetr about 20 minutes it starts to cut out. Once the ice melts, it fires right up.
It has a 4.3l v6 GM engine, 2005 is the year model. I appreciate any help you can give.
