Sounds like a bad fuel pump. I haev seem them get tto weak to supply the presure neede to start the engine, but can maintain enough to keep it running. Use a fuel pressure gauge to verify pressure when it wont start

The first two are " lean bank 1" and "lean bank 2"
the next two are low O2 sensor voltage bank 1 &2 which is probably due to lean condition.
P0102 is a MAF issue-
P0113- is IAT sensor voltage
P0122 is TPS circuit voltage.

Start by checking fuel pressure, change/check fuel filter. You can get the related codes from it being too lean. Check for vacuum leaks as well between the MAF (Airbox) and engine.
