Powerpro 236 issues

I'm having an issue with my PowerPro 236 where it will stop activating HF start when starting, then on stopping the gas valve cycles on and off randomly and torch stays powered up. Often when it's in this "stopped" state the current reading will show minimum current.
It doesn't appear to be related to foot pedal as even after unplugging it the gas valve can be heard cycling.
Generally after a few power resets I can get things working normally again for a while, but it's very frustrating when it happens and seems to be getting more frequent.

Anyone else seen something similar?
