Hi there,
First up, I'd be hooking up a timing light to each plug lead in succession & looking at the flash for any irregularities. If one or more cylinders is showing 'no flash' at any point, remove & change the plugs. You can do a similar test by removing each plug lead in succession & noting any running change. No change equals a dead cylinder, probably the plug..
LPG fuel can be hard on plugs, sometimes needing a colder heat range version.
Let me know how you go. I should be able to talk you through any further diagnosis if needed here..
