Clearly there is a lack of gain on the high side of your sim. The key to debugging this is to examine the currents in the transistors. May be a bad model.
If you post the file and models I could try it out. Which simulator are you using?
PS: Here are some voltages and currents off my sim attached. I hope it will give you some ideas.
