Starting and stalling immediately could be related to the Engine Coolant Temperature sensor.
Have you tried retrieving for diagnostic Trouble codes? Did the Check Engine Light shows while driving?
LPG operations does not involve the injectors and I would be more inclined to believe it is a problem with the ignition system, more likely to be sparks plugs or related items, such as ignition coils.
