The tankless heater fires up when it detects water movement/ flow. I have two of them and sometimes during very cold outside temperatures mine do what you’re describing. If i open and close the faucet once or twice, it picks up the flow and water gets appropriately hot. Doesn’t usually happen unless temperatures are in low thirties or below. My tankless units are in the attic.
This is kind of what I thought might be going on. And mine was installed outside on an exterior wall of the house, so maybe it's an external temp thing.

As said I’d take the head off the shower head and make sure there’s no screen that has a blockage, and run the shower with the head off to clear the line.
It’s possible your valve is loose or bad and not catching every time? Thereby not letting enough water out?
If that doesn’t solve it I’d consider asking the water heater company.
