We show that sustained plasma discharges in the ZT-40M reversed-field pinch experiment can be explained in terms of electron wander in a stochastic magnetic field. We indicate results of a Fokker-Planck calculation for nonlocal electrical conductivity in slab geometry and show that this approach can account for the key anomalies of reversed-field pinch behavior, without needing to invoke a ''plasma dynamo.''
