Got propane?
If it was recently filled, you need to purge the lines by leaving gas valve open for a few seconds as you try to light it.
Did the refer work on propane before?
Since your issue involves all of your propane appliances, I would start with the source. Propane tanks have automatic tip-over protection built into the tanks. Rough roads can sometimes trip this shutoff valve. You can try to reset it by take your tank to a level surface and drop it straight down from a height of 18 to 24 inches. May have to do it several times.
