According to UC3844 data sheet, VCC needs to be at least 16V (plus/minus 1.5V) in order for the IC to start working and 10V (again, plus/minus 1.5V) for the IC to continue to work.

What you have sounds like a classic start-up cap issue. I suggest you replace the small electrolytic capacitor near the UC3844 IC.
