Electrical issue with Noritz Gas Tankless Water Heater

I've got a Noritz NR98SV tankless unit and the hot water will sometimes go cold in the middle of a shower. No error codes have ever been thrown and I've got a water softener and have also flushed it regularly.

I took a look at what was happening and found that the water goes cold because the whole unit turns off and then turns back on about a minute later. When the the unit turns off, the power from the receptacle is out. The circuit breaker does not trip. And then soon after, power from the receptacle is back and the unit turns on. I replaced the receptacle but the problem continues.

Any ideas?

Sounds like there might be a loose connection in the circuit supplying power to the receptacle.
