Have you had all the burners on the stove lit at the same time ?
I ask , because they shut off the supply valve on the the propane tank when filling , and sometimes they ;1 don't fully open the valve when finished , or 2 , open the valve so quickly they trigger the full flow safety valve on the tank, that restricts, or stops completely, propane flow through the system .
To re-set the safety valve , turn off all propane appliances , close the supply valve on the tank, and open the valve VERY slowly , back pressure in the system keeps the safety valve open.
Then light all the stove burners; on high; at once , for a short time , then start the fridge.
