Makes me think its some sort of low pressure issue. I had the shop its been at for the past 4 months, who found that bulletin regarding fuel return lines, replace the 3 fuel return lines, but still didn't fix it. At this point I'm at a loss, I've got one more shop to try locally but of course they can't even get me in until October 13th. I'm totally out of money and motivation to keep at this but I have a loan on the car so I have to fix it even if I'm going to try to sell it. Unbelievable. Any progress?

Today I received a LPFP that I purchased used on Ebay.. it arrived with a huge hole on the bottom of the fuel pump base
I'm starting to think this car doesn't want to get fixed. I was trying to save a bit of money on a used part, but I guess might as well buy everything new.
By the way, I'm not sure if you have seen this post, but it describes exact issues that both of our cars are having. I reached out to the owner on that thread, but so far haven't heard back. Check out this thread if you get a chance:

Any updates on your end? Have you tried getting your injectors bench tested? To see if any of them might not be working properly? That might be the next cheapest thing for you to try, if you haven't already.
