Ethanol gas goes bad VERY quickly. Sometimes it already has moisture in it out of the pump which will then separate and end up at the bottom of the tank, then getting pulled into the motor by the injectors. Water does not burn, so there's the hesitation. It could be electrical but that's hard to imagine. The assembly line is so A to B to C. If it was haphazard they would have these issues ALL the time. Only my old two strokes fouled plugs. But I can imagine a dealer or previous owner putting in Gas Can Gas. That would do it. If it runs smooth at 35 mph for example, I'd just ride a back road for a while and/or syphon the gas out of the tank.
