Do you have any starting/battery issues? Where the voltage drops below 12 volts?
For engine to quit, it has to loose spark or fuel, it has electric fuel solenoid at carburetor, that would kill engine if the voltage drops below 12 volts. best test is to remove it and plug the hole, but if it holds the carburetor bowl on, you would have to find a replace bowl bolt, or remove the inner tip of the solenoid.
