The first thing I would do is drive it till it acted up again and pull codes with the engine running and see if the lack of ignition signal was pressent at anytime.
I would be looking close at the ignition hall sensor at the front crank pulley and the pulley itself as the rubber might be separating from the harmonic balance section and wacking the sensor or the sensor my be weak.
If so .... Time to replace the sensor, pulley, oil pump O Ring and front seal.
The seals and pulley are usual failures at 100 - 150,000 miles. The Hall pickup sensor has a unestablished failure rate here. Its rare that I do one at the shop.
