I like the idea Frank G had of replacing the regulator to one with a higher flow. Do it once and not worry about it again.

Pressure drop through a regulator cools the regulator (think refrigerators) and can (and will) ice up if there is any water in the propane. Does not take much with a small regulator. Had that problem in the 30's, regulator had iced up on the outside which insulated it so inside got even colder. Once I got the ice off the regulator and warm it went the rest of the night. The "on-line" tank was getting low which may have contributed to the problem.
