It could be that you have a bad spark plug-ignition wires are grounding or your coil pack is shorting out... If it were me I would wait until dark ...lift the hood and run the engine at about 4000 rpm ...look very closely at the wires and the coil and you may see arcing ,,, Put an OBD and check codes
