Tankless Water Heater Won’t Start

Weve had trouble with our Bosch tankless water heater since it was installed several years ago. The installers attempted to fix it multiple times, added a bigger exhast, cleaned it, but we keep getting an error code which says not enough gas. It takes multiple reboots to start. Oddly we finally realized, if we turn on a 2nd facuet for about 15 seconds, before starting the shower, it works 95% of the time. Once the shower is going, we can shut off the 2nd faucet Any idea what is going on?
