Intermittent power failures in a new build
I'm with @Tyson, my money is on the utility side. Outages like this are frequent especially if you are in a newer area where there is a lot of construction or in an old area where there hasn't been much maintenance on the lines. Check with the utility company if it is on their side they will have a list of recorded outages, right up to your meter if you have a smart meter. If it is not the utility company then your problem lies somewhere between the load side of your meter and the bus in your main panel.

Good luck
