iPhone 7 plus keeps shutting off after screen replacement

I just did a screen replacement on an iPhone 7 plus. The previous screen was almost completely shattered with a large hole in the upper left hand corner.
After I completed the repair, I turned the phone to find that everything worked fine. The camera, microphone, audio, etc... all worked great. I left it on for a few minutes just to make sure everything was fine, and while I did that it turned itself off.
Now I can't get it to stay on. It'll stay on for anywhere from 30 seconds to 10 minutes, however at some point it will shut itself off. Sometimes it'll shut off when it would usually go to sleep. Sometimes it'll shut off when the lock button is pressed. I've tried disconnecting the flex cable (for the camera, light sensor, etc), and it still does the random shut off thing.
Other than that, there doesn't appear to be anything wrong with the phone. When I leave it plugged in, I don't believe it does this shutdown thing (however I haven't had a chance to test for an extended amount of time).
Has anyone experienced this before, and did anyone come upon a solution?
