Just some thoughts...

Could the EVAP check (one-way) valve be sticking open slightly when warm, creating vacuum loss, then closes once it has cooled down some?

When you replaced the antenna ring did you clean the harness connector with contact cleaner? Although, you'd most likely experience poor starting from cold if that was the case.
