It is pretty clear that the fuel pressure is dropping.
You can measure the pressure. All you need is a yardstick, some clear tubing and some elastic bands. Size the tuning so it can be pushed onto one of the burner jets. Use the rubber bands to hold the tubing to the yard stick. Put water in the tubing. You have just made a Manometer. A very common engineering tool.
Now, turn the gas on. The yardstick will make figuring the difference between the levels real simple. It should be 11". (Anybody that works with this will call that 11"WC - Water Column.)
Does it start out there? Yes is good.
Does it stay at that level with a burner going? No is bad.
Now you just need to find out why it isn't staying at 11". Crud in the regulator is a common issue, but seldom with anything so new. Regulators are typically not serviceable, but the are cheap to buy and replace.
