Possibly a bad connection inside the plug/receptacle.
Start with replacing the ends or get a new cable and adapter.
The receptacle is fine it's only at the adapter on the 30 amp plug side! All the signs point to pulling to much power.
............With 50 amp service you have 2 25 amp breakers on your master panel , you also have 2 heavy copper flat connectors on the 50 amp plug ! When you downsize , to a 30 amp , you've allocated ALL LOADS to one large flat connector , instead of 2 . The plastic housing of the 30 amp will heat UP along with the positive connector and then the resistance starts increasing , the voltage will be reduced because of the increasing resistance(due to heat) , which means the amperage will increase as the voltage decreases ! , jf
