Briane,
Another old guy who has a hard time understanding punctuation and capital free text. Anyway, I hope the problem has been solved. If not, I have a big block V6 in a pickup that had similar symptoms that I thought were caused by lack of fuel. It turned out to be badly burned points. They weren't old, but the resistor wire that is supposed to run between the coil and ignition in mid-60's GMC's was not reducing voltage when the truck was running.
