Buy a NEW spark plug before you do anything else.

Also check the gap before install. Those plugs gapped at the factory

they are not all the same

OP - loosen the gas cap a turn or two. If the cap vent is clogged the
tank will create a vacuum, affecting fuel flow. Clean vent with a
paper clip.

You have plenty of oil in the engine, right. If the motor has a low
oil kill switch that would shut the down engine.
