Runs, stalls, runs, stalls every few miles

[kk2002s]

This morning out of no where car stalled at light, like fuel starvation. It is a sharp turn and as down hill to light. Would not fire up for 5+ mins then finally started and drove fine for 5-20 mins till I got to work.
Started fine and idled normally at lunch.
On my way home turned a couple sharp corners after 10 mins driving and same fuel starvation feeling. Again same 5-10 mins with no fire up then start and drives fine. This happened routinely 4-5 more times until I got home.
I was thinking water in the gas but with some researching I maybe seeing fuel pump failure.
Unfortunately Bentley manual will not cover 2002+ fuel systems very well.
The car is Not throwing any codes.
I did disconnect battery to work on my door 4 days ago but the car ran fine to work the next day
I put it away in garage running fine so I would have to diagnose running correctly until I can get it to stall out again
I don't have any fuel pressure testing tools so unless I can rent

any direction, experiences will be greatly appreciated
Of course I had some great driving planned this weekend
