P0453 & P0643 plus VDC & Check Engine

I own a 2012 Infiniti FX35. It is currently not running because it went into limp mode. The Check Engine and VDC lights are on and the codes are P0453 and P0643. This has happened about 7 times over the past 2 years. Each time it occurs the low gas light has been on either when or shortly before it occurs. Many solutions have been tried: new battery, cam sensor, sensor in the gas tank and a gas pedal sensor. Remaining times the codes were cleared and car was fine for a few months or until I ran it low on gas again. None of these solutions held up. 2 days prior to this time I had a wheel bearing replaced and was told I have cloudy brake fluid. My low gas light was on in the morning but I filled the tank and drove it about 2 miles then parked for 3 hours. Turned it on, drove 2 blocks and then this happened. Any ideas? Thank you.
