Check for insects as advised. If it’s still a problem check the little holes on the burner unit, it doesn’t take much for them to get partially blocked with built up soot and grease, or just dust and dirt. And maybe you need a new regulator, not that expensive. Or it wasn’t a couple of years ago, who knows now?

There is a device inside propane hoses that can get wonky or need to be “reset” for lack of a better term, too. I only learned of this feature by reading user forums, but these are hoses used on appliances that have their own built-in regulator. I only mention it because there are a few show stoppers that aren’t necessarily intuitive, including bugs/insects.

> Could be the hose (!). We couldn’t get the grill working in the camper, and I thought it had to be the regulator, but it turned out to be the hose - the check valve in the connection to the propane tank got plugged somehow, and blowing it out fixed the probelm.

Again, I appreciate all the replies, but the issue seems to be specific to this one propane tank. I will know better this week when I use the other tank.
