I had to roll it out into the street on a level surface to start her back up. The Taurus' fuel sensor will cause that issue on inclines due to its placement in the gas tank. If what little gas is left is pooled up in the back, it will think it's empty.

Not sure where the Z's sensor is located, but it could likely be caused by the same thing. Whether it's a hill, or you're taking hard turns and moving all the fuel to an area where the sensor won't see it.

Just a guess...
