Default Re: Stalling out while driving

I had a similar issue a couple of years ago and I'm still running stock carb/etc. It would idle for long periods and I could cruise around at lower speeds, but highway speeds would cut out and/or die. The cutouts were not sharp like electrical; they were like running out of gas.

I checked all the items noted above and after I successfully bribed my better half to crank the engine while I had the fuel line from the carb in a clear jar, the low fuel volume and lack of consistent flow, convinced me the mechanical pump was bad. I swapped the pump out and it fixed the issue.

Just FYI. Good luck.
