Car dies at idle after reaching operating temperature

What is your question?

Changed spark plugs and wires, changed coolant temp sensor, changed fuel pump already. After it dies at idle it doesn't want to start again right away. Then once started again it sits at about 750 rpm revs up to about 1100 rpm and back down again. This is without AC running.

Possible vacuum leak.

Thank you very much. That was our next guess too. Hoping it isn't compression problems.
