LTC4366-2 dont work

Hi! I developed simple surge stopper circuit using LTC4366-2, but it doesnt work on the pcb, althouht it was working properly in LTSpice simulator. What is the problem? Also, i noticed that circuit started up when i toched the floating ground point of LTC4366 by oscilloscope's probe common pin. I tried to increase and decrease all capacities, but this didnt lead to changes. I tried input voltages in wide range from 30 to 150 volts.
