Not sure what you mean by a "hybrid kit". An add on electric heat element? Heater bypass plumbing? Please explain further.
Typically when the faucets deliver hot water briefly and then goes back to cool, the problem is either a heater bypass valve open or a secondary faucet has both hot and cold taps open, allowing hot & cold to mix. The latter occurs often when an external shower or spray faucet is left on (hot & cold taps open) but the flow is shut off at the spray head.

Another possibility is a long run between the hot water tank and the faucet that you are using. In our unit, the plumbing runs beside a furnace air duct. That portion gets warm quite quickly. But the rest of the line remains cold. If you run the faucet for an extended period, does it get warm again? If so, then possibly everything is normal.
