Sometimes when that happens to my grill, I shut off the burner valves,
and relight the grill and it works fine again. It seems like something
was blocking the lines going to the burner intermittently.


That is because something WAS blocking the gas flow. The new tanks with OPD
valves suffer from this when very full and the valve is opened quickly. The
overflow protection device impedes gas flow. Shutting it off and slowly
opening will usually take care of it.
