Hi there. Your vehicle has a sequential fuel injection system. When the computer detects a fault, it converts to port fuel injection (bank to bank/limp mode). The most likely cause could be an electrical short in the odd bank of the fuel injection system. A wiring harness short or shorted fuel injector may be the cause. I recommend having the fuel injection system inspected and the codes diagnosed in order to resolve this stalling issue.
