This problem has seemed to get worse as time goes by. (Propane Throttle Body system) When trying to start, the engine fires off immediately but dies off, after many attempts (10-20) it will finally start and run. It runs very good and smooth once started with the exception of when the throttle is released it seems like its going to die but always catches back up and doesn't die. If it is turned off it will start back up no problem unless 5-10 minutes go by, the start issue comes back.
Replaced propane filter no help.
