  We describe two observations of the nova-like cataclysmic variable AC Cnc
obtained with {\it Kepler} during its revamped second mission ({\it K2}). Using
the {\it K2} 1-minute cadence mode, the data were obtained during Campaigns 5
and 18. Campaign 5 (C05) lasted from ${\sim}$2015 Apr 27 to ${\sim}$2015 July
10, a total of 74.8 days, and yielded ${\sim}$106,000 measurements. Campaign 18
(C18) lasted from ${\sim}$2018 May 13 to ${\sim}$2018 July 2, a total of 50.7
days, yielding $\sim$72,000 measurements. The C05 light curve reveals two
`stunted outbursts' having properties consistent with stunted bursts observed
from the ground; a stunted burst was underway during the C18 observation when
it ended. During a stunted outburst, the primary eclipse is found to increase
in depth but the residual brightness at mid-primary-eclipse remains nearly
constant. By contrast, the secondary eclipse retains the same depth but the
brightness at mid-secondary eclipse increases during outburst, following the
orbital variations of the out-of-eclipse light. The eclipse ephemeris is
statistically consistent with historical ephemerides and shows only marginal
evidence for a period change. On the basis of the {\it K2} data, we can not
confirm a previously-reported non-orbital periodicity in AC~Cnc.
