^^^^^ I agree, I'll bet it's the regulator. Mine did the same thing about 2 yrs ago, luckily, somebody figured a good place to toss a neglected bbq was behind my work, I took the reg. with hose off this junked bbq and hooked it up to mine. still working today.
I'm getting a Nat. GAS hookup any day now, and have the natural gas bbq (almost) ready to go, the minute that happens, you can have my propane bbq and tank.
