Fuel pump or regulator. Put a FP gauge on it and see where the pressure is when running then pull the regulator vacuum line off and see where the pressure is. Turn the engine off and after 5 minutes check the pressure and see how much it maintained.

Well my 7 days off just turned into 2 days off, so i dropped it off at my mechanic. He pretty much echoed what you said, cats checked fine, if it were ignition related it would probably throw a code, so he thought fuel.
If I have to replace the pump is there one worth buying over the factory that doesnt require much modding? Really would like to put an external on so if it were to ever go bad again I would have to drop the tank.

Yeah those things suck. But atleast now you know, and so do we if the same problem is encountered. How'd you find it, propane bottle and scan motor?

mechanic found it somehow, damn thing still not running as good as it was. Think im going to go ahead and replace the fuel pump and regulator, if nothing else its good preventive maintence.
