Maybe someone else more savvy can weigh in but a cursory google search involving the latest US and Russian suits say between 7-9 hours (I got the 9-hr. figure from Wikipedia involving the Russian Orlan-M design). One has to factor in what the astronaut is doing as strenuous activity would obviously require more oxygen, carbon dioxide removal, water, etc. My search didn't go into future designs.

It is worth pointing out that both US and Russian suits have the capacity to "recharge" during the EVA, which extends the EVA time. Without the spacecraft around for recharging purposes, the actual survival time would be less.
