It sounds like the drive belt may be stopping for some reason. Any one of the components freezing up could be causing it. The fact that shutting it off and restarting helps, could make the A/C system highly suspect but there has to be issues with the belt and tensioner for it not to stall the engine.
All this would have to be verified during the problem.
