Sudden loss of engine power when turning.

My Aurora is suddenly loosing engine power when i am turning a steering wheel and accelerating in slow turnes its like if something cuts off the fuel at the moments usualy the power gets back when i am straighting out the wheels.(Most of the time it happens in the first turnes after the cold engine start.)
I noticed that it gets worse when the fuel tank is low on fuel.
Did somoene had or have simiular problem. I would like to get some advise.
Thanks.

First thought sends me to the gas tank and maybe a leaky fuel pump, line or line connection in the tank but I have never heard of this B4.

Fuel pressure test might be in order to verify.
