Again after several months of use over the summer while disconnecting today I found it failed again.
FYI I have inspected and tighten all terminal I could find.
Any ideas.

That is a HEAT problem.
Heat is caused by resistance and current.
If you have a poor (high resistance) connection it may start as a slightly high resistance connection, but as it heats up the resistance increases, so the heat increases, and on, and on.
The other thing that resistance does is drop the voltage to the downstream loads. Now you may that lower voltage would mean lower current, and that may be true for resistive loads like the heating element in the water heater or fridge, but for those appliances like Air Conditioners and Residential Fridges that try to do constant work, as the voltage goes down the current has to go up to continue to do the same work. This adds to the heat problem at the high resistance connection.
So:
What loads are you running in the RV?
What voltage is normally delivered to the RV?
Verify your wiring in your home RV pole/breaker box. Especially make sure the 30 amp connection is powered through a 30 amp breaker, not one of the 50 amp hot leg breakers.
Replace both the RV end and the cord end at the same time.
