Are you in a double, single or triple wide ? Have you checked main duct trunkline(s) to see if there's an opening ?
Does burner flame appear to be big enough across length of burner tube ?
Is burner flame same as before ?
Thanks,
Robert

I figured it out. There was a spider nest tightly compacted into the gas jet coming into the burner. Would have never thought of that!
Thanks!@

LOL, yep, that's where my questions were heading. Usually you'll see a difference in burner flame and then I say look for spiders web in orifice at burner.
A search would locate plenty of those suggestions on here.
Spiders love those during off season.
Glad you found it and now know a common failure location.
Take care and best wishes,
Robert
