When you switch from LPG to Petrol the engine should not turn off. Either Petrol may not be sufficient in the fuel tank. or. You have mentioned as if this happens only when the car is in Neutral idling. That means while in running in gears if you switch to Petrol I think your car will not turn off (as it is in gears) but it will take one or two seconds to get fired by petrol and it will move with a jerk. If it is so the problem may be in the selonoid valve in the gas kit (vapouriser) It may be obstructed with dust particles and may not comletely close the gas while you switch to petrol. So gas and petrol combines and make the engine turn off. There will be a valve in the gas tank also. That will close the gas and the gas in between the tank and vapouriser should get empty and then only your engine fires the petrol. That is why while you are driving the vehicle pushes away the in between gas and the starts to run in petrol with a jerk in few seconds. If the problem is this just simply clean the selonoid valve in the Vapouriser by flushing the gas after removing the valve.

If you want to confirm whether this is the problem, While your vehicle is running in Neutral idling in LPG, if the wire coming to the selonoid valve on the vapouriser is pulled out, the engine should turn off immediately. If it is still running means the valve is not closing the gas completely. Then you should clean the valve.

Mr. JothiBasu, Thanks for your answer on my question, I am confident that Maruti Wagonr Duo is not desinged in a way that i mentioned in my question, but to my surprise, when i gave my car for serivice to maruti showroom, they told that wagon R duo desinged like this. i was shocked and challenged them thats not the case. I am not sure where to go and whom to approach for my problem to fix.
