KV,
C6,7,8,9 I changed to 47uf 170m ohm. It is taking a very long time for the design to 'converge'. Power supplies do not operate right for some time after power up. By changing to 47uF it takes 5mS for the supply to stabilize. There is too much ringing in the LC so I reduced the Q. C6-9=170m ohms and HV primary =50m ohms. Other wise it takes millions of cycles to see how this thing will operate.
Also I connected the top MOSFET-gate.
It is operating how I think it should. Probably should have diodes on "outA" and "outB".
