Can you be more specific??? Did you check your spark plug wires.They could be frayed and start to arc. You could feel bucking and loss of power because of this.

A sudden loss of spark can be caused by a faulty crankshaft position sensor.

If the computer loses the signal from this sensor, the computer won’t operate the ignition system.
