Most likely not the problem......but thank you for the help
In AC and LPG mode the fridge lights are on, the burner is on in LP mode and still no cooling.

The way you describe it is like the 12V battery voltage is low. You need to check the voltage at the converter output, and at the battery when plugged in. Your charge voltage may not be reaching the battery, and then when the battery goes low, the fridge shuts down.
It might not be the problem, but it's worth checking your battery voltage to see, and it's the source of a lot of problems that don't look like a bad connection.
My fridge was not faulting, but the idiot light dropped to one bar out of four while I was plugged in, and I found a loose negative connection at the converter. I wiggled the wire, and the inside lights all jumped up in brightness. Tightened the connection, and all was well.
