Rich condition, possible low fuel pressure?

[AVG]

So I've had this CEL for over a year now and it's getting to a point where I can no longer ignore it as I finally stalled while idling at a red light yesterday. Using a basic OBDII scanner I've also noticed that the fuel pressure sits at 45-50 even when driving around, and according to information I can find it should be more in the high 50s to 60s range, but idk if that's even correct or important since detailed information on these things can be tricky to find.

I've already replaced fuel pressure sensor and maf sensor, both of which made it go away for like a month or two, so it's also possible that parts just keep sequentially failing. But I'd like to ask just in case there's any other common issue I should know about rather than just throwing money at it until it fixes itself.

Thanks all.

64 psi is needed
Your pump is weak or filter clogged or both

At 50 psi the fuel is dribbling out of the injectors Instead if atomizing into a fine
Mist .. not good

45-50 Psi is waaaay too
Low

I use Bosch pumps (own) or ac delco or carter try to get made in Germany or
Made in USA
Replace strainer pump and filter

So I cleaned the MAF sensor out on Wednesday, the code didn't go away on its own like it did when the fuel pressure sensor went bad but I cleared it and it hasn't come back since. Also trying to remember what the live data read, I think both the long-term and short-term fuel trim values were quite large, although I may be misremembering things. So I will look into that.
