Do you not start on petrol and switch over automatically

Most if not all LPG systems do a petrol start and then switch to LPG quickly after that. If yours is a petrol starter, you may have an issue with the non return valve of the petrol pump starting to leak so the petrol drains back to the tank.

If that's the case there could be two things going on, wear of the seal or dirt caught in the seal area.

Other option is injectors that start to leak a bit and the petrol disappears that way.

If it is dirt in the fuel system, running it on "clean" petrol like V-Power and the likes could help. Run it on petrol for a 100 miles or so. Also maybe chuck some fuel system/injector cleaner in the petrol tank and do a 100 mls run with it. That would hopefully flush the petrol system clean. MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!
