Either the powersteering pump is using all the power, or the egine is fuel starving.

You may have something in your fuel tank sloshing around and cutting off fuel to the pump.

I've found chewing gum, foil from additive bottles, sugar, marbles, sand, and pure sediment from years of use. (These were all Mercedes gas tanks). Some of these wrap around the pump and get sucked randomly into the intake during turns and clog the prefilter.
