I agree with the others that there is nothing wrong with running the fridge while towing. If it is going out while going down the highway, then you have a problem somewhere.
My question is "has the fridge going out always been a problem when going down the road"? Or is this something that started happening later on after it was new?
This is what comes to my mind as what to look at.
1st, make sure the little pivoting cover that you open to view the burner flame is closed.
2nd, if it is, then I'd check the ignitor/flame sensor. The igniter also acts as a flame sensor. It sends a signal to the control box that you have a good flame. If the control box does not receive that signal, it shuts the gas off.
There are two things to look at on the flame sensor. First make sure the ignitor's electrode is clean. If it is dirty or has carbon/soot on it, that can impede it's ability to detect a flame. It may work OK in a calm conditions, but when going down the highway and the burner can area has more airflow, the flame sensor may be having problems sensing the flame. You can clean it with some very fine grit emory cloth or sandpaper.
Next make sure the mounting area where the electrode is attached is clean. This is the electrode's ground. If the place where the electrode is mounted, is rusty or dirty that can also affect the flame senor's ability to function.
If all that checks out and/or the fridge has always gone out while towing, then I would suspect an issue with the installation. The burner is getting blown out by excessive airflow. Look at the burner can area. It should basically form a shroud or "chimney" around the flame. It should protect the flame while allowing adequate airflow at the bottom and top.
