Sounds like fuel pressure or ignition.

It could be that something got gummed up during the storage so I'd start by checking the fuel system pressure, WUR cold pressure and hot pressure. This is done with a set of CIS gauges which are about $100 US. A search here should provide the design pressures.

If that tests good, try to find a CDI box you can swap out.
