Welcome to 2CarPros.

Any time spark is lost, my first suspect is the crankshaft position sensor. Now, testing it really isn't that hard, but it requires a live data scanner. Basically, plug in the scanner and check for an RPM signal. If none is found, the sensor is the most likely cause.

Here are a few links you may find helpful:
