We study transport and relaxation of spinless fermions with long-range Coulomb interactions by out of equilibrium dynamics. We find the relaxation is continuously slowing down with stronger coupling V and there is a transition in the transport type. For intermediate V , the system displays normal diffusive transport, however the relaxation time is long and scales with V in power laws. For large V , the relaxation time diverges exponentially with system lengths, featuring a MBL-like phase, while at the same time it supports subdiffusion transport. We attribute the slow relaxation to possible bound states, which become slower with increasing V .
