Gas stopped working

Hello
I was using the gas cooker in my 1999 Chausson (2 jets) last night. I switched on the boiler to heat the water for the wash up and the gas stopped working- no gas to any appliance.
Is it a coincidence that it stopped with the water heater (truma) being switched on?
Where do I start to try and fix it?
My first post here!

Thank you

1. Have you gas? Stupid question maybe, but have you gas in the bottle?
2. Regulator, possible it has gone faulty. Can happen suddenly as oily deposits block the orifices.
3. Have you accidentally turned a tap off on the manifold? Unlikely you’ve turned all off though.
4. Have you been in the gas locker? Maybe kinked gas flex pipe/tripped the on/off button.
5. (Not likely as not cold enough yet) if you run butane in your van it will stop gassing off at temperatures approaching freezing point, even above zero degrees. Use propane instead, it won’t freeze until temps are extremely low.

Working all week so only got around to checking gas today. Changed the regulator and had a lovely flow of gas!
