How does this thing contact internet when power is lost.?

Okay, the answer depends on how and why you are using it. I am using it on a GFCI outlet that waters my hydroponic gardens so that outlet often trips but the rest of the house has power. Great for me but perhaps not for you. If the entire house is without power then you would need to have a UPS unit providing power to your modem and wifi router in order for you to still get the message. Having said that, this thing is awesome and texts me when the outlet trips and texts me again when the power is reset. All for an amazing price!

Why not just be a power source for a few hours so WiFi still works and my bearded dragon doesn’t die while I race home?

Why not just be a food processor so my smoothie will be ready when I get home? This is a $50 alarm. If you want a backup power supply, get one of those. They cost hundreds or thousands of dollars.

If the power continues remain off will it send a message every minute until it comes back on?

It will send a message when the power goes off and then another when the power comes back on.

I want to use this connected to a Verizon WiFi hotspot on my boat - will it use up my monthly data, or only when it connects to send me an alert?

This device sends a heartbeat once a day to the cloud for the central monitoring service. It will also send one OFF alert when power goes out and one ON alert when it comes back on. Your data allowance will not be used up.
