Engine stalling, engine light

[CJ51974]

On my 2000 beetle I have had the engine stalling a few times a day, sometimes when idle it will almost stall. The engine light went on, codes P1137, P0322. I was thinking maybe fuel filter or pump, but I dont know, any suggestions?

Thanks, now the motor wont start at all, it sputters, I feel like it may be a bad fuel pump, id hate to replace the pump and filter and that not be the problem, any diagnosis I should do first to rule out any other possible issues or confirm the bad pump?
