I just drove my 83 dolphin down from alaska to Idaho, over 3500 miles and all I had to do is add gas and go!!! AWESOME. However, when I got close to my destination, It stalled out on me a couple of times. This happened during big head winds and hot temps, although the temp gauge never went up to high. It started when I would be in first or second and it would sputter a bit, but then when I put it in 3rd or 4th it would run great. Then about an hour of driving later it did it while in 4th gear and I had to pull over because it wouldn't run. Then I started it back up got it going and was able to make it to a gas station. I put new gas (it still had at least a quarter tank, and the lever has been lower than that) and drove another 100 miles with no issues. I was thinking maybe a fuel filter maybe or clogged fuel line?? Or maybe something with the exhaust which is severely falling apart, an almost cloggged catlytic converter and no muffler hooked up right now? I have also noticed ever since the Yukon when I started it up after a construction stop, a smell of gas in the cab. It took a bit of cranking and smelled like I flooded the engine, but the smell of gas has been persistent ever since. Hopefully someone has some ideas, thanks in advance!!
