Thanks for all the reply’s. It will do this at around 40 degrees or below. I have determined the pressure or flow is low by lighting the stove top. When I do this the flame will drop very low but doesn’t usally go all the way off.
Last night it dropped pressure about 3 times within 4 hours. It is connected to a full 100 gallon bottle and this problem didn’t start till I had it delivered. After it dropped for the third time last night I switched it back over to one of my smaller bottles and didn’t have any further problems though the night.
I now believe the problem is in the bottle but do not understand what is happening so I can convince my gas supplier that the problem is in his bottle.
