my boiler turns it self off after about 20 minutes. they is no pilot light so i try to light it back up and as soon as i let go of the control button the pilot light goes back out. if i leave the boiler about 20 mintues then try it again it comes back on, then after another 20 mintues of being on does the same thing. this is on a gas potterton flamingo 40
