We have searched for pair production of the supersymmetric partner of the top quark (stop) in $107\text{ }{\mathrm{p}\mathrm{b}}^{\ensuremath{-}1}$ of $p\overline{p}$ collisions at $\sqrt{s}=1.8\text{ }\mathrm{T}\mathrm{e}\mathrm{V}$ collected by the Collider Detector at Fermilab (CDF). Each stop is assumed to decay into a lepton, bottom quark, and supersymmetric neutrino. Such a scenario would give rise to events with two leptons, two hadronic jets, and a substantial imbalance of transverse energy. No evidence of such a stop signal has been found. We exclude stop masses in the region ($80\ensuremath{\le}{m}_{\stackrel{\texttildelow{}}{t}}\ensuremath{\le}135\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/{c}^{2}$) in the mass plane of stop versus sneutrino.
