Intermittent Stalling B58

Currently having an issues where my car (2017 BMW 440i F36) intermittently stalls out while driving, only codes are 1-6missfire and it feels like the car runs out of fuel.

If you leave the car for a few hours and come back, you get correct fuel pressure and all is good.

Spool FX150
Reflex+
Spool stage 3 LPFP DIY
Precision raceworks 750cc injectors(PORT)

Want to mention that the LPFP is rigged off of a HOBBS switch.

Sound like an EKPS to you? How can I test this?

Just asked my tuner about this

This could be your EKP module or fuel pump module that the EKP wire connects to.

Whos your guy's tuner?

MHD by default runs the EKP at 90% load and my tuner said he runs it at stock which is lower than MHD

I've having the similar stalling issue of my car (2017 F34 with B58) while normal driving. Car is stock except Stage 1 / 91 tune and intake by Dinan. Car has ~ 96K km (~60K miles on the clock). The intermittent stalling had started roughly 4 - 6 weeks ago and it does happen at idle and at low RPMs (less than 2k RPM) at highway speeds. Frequency of stalling is around every 30 - 50 seconds once engine warms up (not as much on cold). Any recommendations for at-home testing for the culprit? Thanks!
