  The most puzzling aspect of the 'strange metal' behavior of correlated
electron compounds is that the linear in temperature resistivity often extends
down to low temperatures, lower than natural microscopic energy scales. We
consider recently proposed deconfined critical points (or phases) in models of
electrons in large dimension lattices with random nearest-neighbor exchange
interactions. The criticality is in the class of Sachdev-Ye-Kitaev models, and
exhibits a time reparameterization soft mode representing gravity in dual
holographic theories. We compute the low temperature resistivity in a large $M$
limit of models with SU($M$) spin symmetry, and find that the dominant
temperature dependence arises from this soft mode. The resistivity is linear in
temperature down to zero temperature at the critical point, with a co-efficient
universally proportional to the product of the residual resistivity and the
co-efficient of the linear in temperature specific heat. We argue that the time
reparameterization soft mode offers a promising and generic mechanism for
resolving the strange metal puzzle.
