hay.
I had a problem just like that, it turned out that the power drain from the battery was turning off the gas valve, so i fitted a second battery and ran the egnition and lights off of that. it didnt cut out then. hope this helps. :D

so how did you do that not to good with electric did you just re route the wires i ahve a second battery fitted with nothing going onto it thanks for the reply

If your second battery is only for the spots and stuff then wire it up using a split chrage relay (£10 ish from towsure) so that it only gets charged by the car when the alternator is putting out over 13volts.  Just fitted one into sister's car for towing and it works perfectly.
