My 1990 New Yorker runs fine, then goes through this stage of losing power.

What is your question?

My New Yorker will run fine for a day or so, with a miss once in a while. Then it goes through a loss of power, wanting to stall, or stall and not want to start? New fuel pump, and filter. Pressure is 45 lbs., New plugs, wires and coil?
