Other problems like low gas pressure a loose or faulty thermocouple or a gas control valve that s not working right can also cause the pilot light to keep going out.
Pilot light goes out in wall heater.
If your pilot light re lights easily after going out overnight it s possible it was blown out by a draft.

You can fix this easily by moving the thermocouple closer to the flame.
We know those issues are pretty vague.
Sometimes the tube might be partially clogged and supplying very little gas for combustion no wonder your pilot light keeps going out.

Thermocouples work by producing a small amount of voltage when it is heated.
Pilot goes out the heater won t operate properly if the pilot flickers is too weak or goes out and the cause could also be blockages in the pilot tube.
