LPG starts but the cuts out. Runs well on petrol.

I’ve looked at solenoids and wiring to the tank.
Tank is full. Not sure what else to check

G’day FR Mate!
My limited knowledge of LPG systems would lean towards a failing LPG solenoid or your water radiator levels too low allowing the condenser to air pocket up and freeze possibly?
We do still have one old LPG system forklift at work that during very cold Victorian winters requires a hot kettle of water poured over its condenser to keep from freezing whilst the donk reaches operating temp.

X2 check water levels?

Have you checked the Tachometric Relay (aka LPG Safety Switch).

Also most problems Ive found on LPG systems have been electrical
some are too quick to blame the gas.
What system do you have direct sequencial or the older style???

If the older style then maybe put a gasket kit through the converter.
