I have a 91 Harley FXSTC. It’s dying while I’m riding it likes it’s running out of gas. I’ve replaced the intank fuel filter, the fuel cock, and rebuilt the carburetor and still have the problem. The bike starts and idles good but when riding it down the street it shuts off and then kicks back on. Could this be an electrical problem or is this definitely a fuel problem?

Confirm that your fuel line is not collapsing and that your gas caps are vented. Also, verify that you have proper float height.
This can also be a charging system issue, so test your charging system.
If all this tests out, remove the white wire from your coil and try running a jumper wire from your battery positive terminal to the same positive post of your coil. Make this a secure quick release because you will not be able to kill your ignition wired this way (bike won’t turn off).
If the problem goes away (wired this way) you have a wiring issue in your harness to diagnose. If the problem still exists, you may be looking at a bad ignition.
