If it doesn't repeat the sound while the engine is running, especially accelarating or decellerating, it is probably related to the starter pinion gear or the flywheel/flexplate ring gear. When the starter gear engages the flywheel/flexplate, there is a small portion of gear tooth missing. It starts to catch and slips, slamming into the next gear and then engaging. Eventually, you'll lose another and yet another tooth, producing a dead spot to an extent the car won't start.

I had replace Bosch Platinum plugs with Volvo plugs to remedy miss firing. The Bosch Plugs worked for five to six months before I noticed the engine shuttering during acceleration, and a mechanic at a Volvo dealership told me that only Volvo plugs would work. The advice seemed a bit odd. Although, the problem was eliminated with the Volvo plugs.
