2010 Silverado electrical problems

[Chevyhead89]

I have a 2010 Chevy Silverado 1500 LT. The problem I’m having is that after it sets for awhile it want start back up. Also the last time I drove it,I let it set for about two days. When I went to start it back up the radio wouldn’t work. And the battery still goes dead on it. Does anyone have any idea what this could be.?

Have the battery load tested.
Have the charging system tested.
If both are good test for parasitic draw.
