If it's not the coil then you have dropped a valve, these dual fuel engines really aren't made for running on LPG.

to be honest ive never worked on one,but i'd probably treat it like any other.1st step would be code reading it for any fault codes.followed by a valve clearance check and compression test before digging into fuel pressure and live readings.does it miss on both fuels?
