Sounds like we have some larger issues but let's address the stalling on U-turns first.
I would suggest we start with checking the fuel pressure when this happens because I suspect we are losing prime on the fuel pump due to the fuel sloshing to one side of the tank and it sucks air, stalls the engine and then it restarts when the fuel is back in the bottom of the tank.
Here is a guide that will help with this:
Let's just start by checking the pressure when this stalls in a tight turn and go from there.
However, other issues such as poor fuel mileage and poor starting may be caused by aggressive driving so we will need to ensure the base engine operation is okay, such as compression.
However, the hard starting at certain fuel levels may be related to the fuel pressure so we need to start with this and fix that issue and then we can get a post started just for the issues that are left.
