  We present the Transiting Exoplanet Surveying Satellite (TESS) light curve of
the intermediate polar YY Draconis (YY Dra, also known as DO Dra). The power
spectrum indicates that while there is stream-fed accretion for most of the
observational period, there is a day-long, flat-bottomed low state at the
beginning of 2020 during which the only periodic signal is ellipsoidal
variation and there is no appreciable flickering. We interpret this low state
to be a complete cessation of accretion, a phenomenon that has been observed
only once before in an intermediate polar. Simultaneous ground-based
observations of this faint state establish that when accretion is negligible,
YY Dra fades to $g=17.37\pm0.12$, which we infer to be the magnitude of the
combined photospheric contributions of the white dwarf and its red dwarf
companion. Using survey photometry, we identify additional low states in
2018-2019 during which YY Dra repeatedly fades to -- but never below -- this
threshold. This implies relatively frequent cessations in accretion.
Spectroscopic observations during future episodes of negligible accretion can
be used to directly measure the field strength of the white dwarf by Zeeman
splitting. Separately, we search newly available catalogs of variable stars in
an attempt to resolve the long-standing dispute over the proper identifier of
this system.
