Motivated by the anomalous c-axis transport properties of the quasi two-dimensional metal, \rm Sr2 Ru O4, and related compounds, we have studied the interlayer hopping of single electrons that are coupled strongly to c-axis bosons. We find a c-axis resistivity that reflects the in-plane electronic scattering in the low and very high temperature limits (relative to the characteristic temperature of the boson T\rm boson). For temperatures near the T\rm boson, a broad maximum in the resistivity can appear for sufficiently strong electron-boson coupling. This feature may account for the observed ``metallic to non-metallic crossover'' seen in these layered oxides, where the boson may be a phonon.
