ok went into a shop everything working fine ....came back 5 mins later and no power steering
........check the usual suspects..drive belt and fluid...both fine.........small amount of fluid below pump on top of alternator.with cap off power steering reservior and engine running there is no fluid circulating.pump is not noisy and at a bit of a loss as to why it would suddenly just stop.any ideas would be welcome as next step is to change the pump.
