Some things to consider:
The Spark has a history of losing connection with the flight battery, some attribute this to the unsuitable small fixings on earlier manufactured batteries, DJI claim its users not fixing the battery correctly before flight.
What were the weather conditions? The downward facing sensors, VPS, will perceive a layer of mist as a solid object, eg the ground. In such an instance the Spark may interpret this as a crash condition and shut the motors down.
The number of available satellites and those in use should not cause the Spark to shut it motors down. As the Spark (unmodified) uses two constellations of satellites, GPS and GLONASS, seven satellites is actually quite low as ideally it should acquire a minimum of six from each constellation, but in the event there are insufficient satellites the Spark would revert to ATTI mode and still be easily controllable.
An upload of your flight log will allow those versed in its interpretation to help give you a more definitive answer for your unfortunate failure.
