Lochinvar Knight xl

I have a Lochinvar knight xl boiler and are getting a no flame ignition lock out.

We get a flame for a little bit but then it cuts out.

I have confirmed that flame sensor, ignitor and integrated control (mother board) is working.

Gas valve was replaced a few days ago but still the same problem.

Any ideas why?

    Check gas pressure, both static and when it is trying to light off. Check it it right on the gas valve taps.
