New plug,check that the fuel pump is ok. If it's pumping fuel then sounds like something stopped up in the carb. All it takes is a little piece of trash in the jets.If that doesn't help,then could be a problem on that old ecm module that fails. Item #18.http://www.partzilla.com/parts/searc...GHT/parts.html Or possibly the limiter(#15) right next to it. Pull the black wire and see it that solves it. They can fault and limit in forward range.
