My El wagaon is cutting out on LPG, she waits a couple minutes and it goes again for a km or two and then stops again(my wifes driving it, I'm away from home)
I'm going to get her to try running it on petrol to see if that is OK.
Any obvious things that could be wrong with the gas, its the weekend of course so no garages are open.

The wife tryed it on petrol and it's still cutting out, wait a few minutes and away it goes????
So it's not the convertor freezing up

check the spark side,coil,leads---sounds like a break down in the spark system,read the other posts in the lpg 6 cylinders.

it just stops dead no coughing or spluttering and starts up sweet again
