Well, thanks for the replys

I really need to do some troubleshooting here before I throw money at more parts.

I have a checklist...

Pull the outlet side of the pump hose off and use the started to see if its putting out the fuel it should.

Pull the fuel pickup in the tank and see if there is anything clogging it or if its possible it could colapse.

Check the lines and connections for any obstructions or leaks.

Check the tank vent.

Check the stator to rotor clearence to see if its a spark issue at speed.

Check the powervalve size.

Make a run without an air cleaner (new)

Finally, get a fuel pressue gauge. This will take the better part of an evening, if anyone has any other ideas let me know.

Thanks again
