Is that code for low gas pressure or low oil pressure? I'm not sure if your unit has a pressurized oiling system but, that would cause it to shut down to prevent internal damage. Check the oil level in the unit, make sure it's full.
However, since you mentioned the stove going out, I'm leaning towards gas pressure problem. But, it wont hurt to check for proper oil level just to eliminate that possibility.
Oh, one more thing - does the stove re-light right away, or does it take awhile before you can re-light it?
