Complete Power Loss

There is a log file with a lot of info on your phone/tablet.

But from what you are saying I asume you are not using airdata.com for monitoring the data after each flight. It is highly recomended to use such a service so to avoid things that could happen in your next flight and all logs are automatically uploaded from your device to the web service. You just have to take tour time to examine them.

I always look in to the logs after the day I fly. Primary for how the battery is depleted trough the flight as well the cells deviations. Also for any warnings that can be missed while in flight. This way I know which batteries are not reliable for certain type of flights usually where a high power peak output may be needed at certain moment which could cause battery with high cell deviation to shutdown and if the battery have some noticable cell deviations in previous flights I don't use it in such of conditions as high winds or if I need a high speed flight. For those I only use the most reliable ones which usually are the newest.

I recommend you or someone with experience in log monitoring to examine your last flight as there still may be a problem somewhere in the system. If so after you rebuild the inspire it will definitely do the same in the next flight with similar conditions.
 

When you get it all put back together, I would do an extensive performance test at very low altitude until you are reasonably sure no electronics were damaged but visually undetectable.
