    One common cause, considering your input, would be the crank position sensor. Many folks damage them when removing their oil filters, using a tool. Due to proximity, the tool can apply excessive pressure to the sensor, causing intermittent faults.

    Good luck,

    The light is telling you that a DTC code has been logged. Pull the codes and see what ECM is trying to tell you.
