We propose ToO observations of a bright classical nova {CN} in outburst using the STIS echelle to obtain ultraviolet spectroscopy while the source is X-ray luminous. The data will complement our existing ground based optical/infrared and Swift X-ray CN programs and provide continous spectral information from X-ray to the IR during this important X-ray phase for the first time. The UV spectroscopy is a critical bandpass that enables determination of ejecta physical properties, including the elemental abundances, mass, and structure. This information provides insight into the role of CNe in the isotopic enrichment of the interstellar medium, pre-solar grain abundances, details on the mass and composition of the underlying white dwarf, needed checks on hydrodynamic models of the outburst, and constraints on the relationship of CNe as SN Ia progenitors. UV data are key to these analyses, providing the only opportunity to observe strong carbon lines in these objects as well as direct measures of the interstellar reddening. With slit spectroscopy from 1100-3100 Angstroms, HST is currently the only facility that can fill this important gap in the spectral energy distribution.;
