Re: Stalling out while driving
AP - I have driven my 64 1500 with a 305 V6 for over 30 years (more and less, less now), and the only time it behaved as you describe is when the small ceramic type filter at the carburetor was getting plugged up. If you have the original carburetor and this is your only filter, I would start there because it the least expensive possibility. This started happening as the truck (and gas tank) aged, and was solved with a larger in-line filter that gets changed when I think of it. I have had several fuel pumps go out in various ways - more often lately because old pumps don't seem to like the new gas. Usually, the truck just dies and won't start more than once while it uses up the little gas left in the carburetor. But one time, the diaphragm sprung a small leak that was spraying fuel out the small vent hole. I knew something was wrong because the truck was using a lot of gasoline, and I was lucky that it didn't catch fire or blow up. Changing the fuel pump takes about 15 minutes with some experience, and I carry a spare. If all else fails, check the points. Burned or eroded points can cause many different symptoms.
