Was Batmans newly formed yellow logo a 60s influence and why has it been out of favor for so long?

The 60s is characterized by bright colors, and since the logo was changed in that time it stands to reason that it was indeed a cultural influence.

Why is not present in any Batman comics since The killing joke?

It was created in the 1960's as part of a new look to Batman. However over the years it has gone out of favor as his overall aesthetic is intended to be one of darkness and seriousness so the bright yellow oval no longer fits. That said, there does tend to still be yellow highlights used in various ways.
