The cut-out problem can often happen from residue building up on the burners inside the lighter. No butane is perfectly clean, all of them will leave residue behind after a while. The sticky, oily residue traps particles of god-knows-what and forms a nice brown gunk that clogs jets and screens fast.

Blowing out the jets will often dislodge enough of the gunk to allow proper passage of fuel, but sometimes it doesn't do enough. Personally, I disassemble mine and clean out the jets using isopropyl alcohol when they gum up real bad. It's a painfully slow and tedious process (talk about lots of little things to lose), but I've got all sorts of lighters that are still working after 5 years.

I would not recommend that for anyone to try though, there's enough things you can lose or damage to ruin a perfectly good lighter. I'd take it to your local B&M or send it back to the manufacturer for cleaning.
