Dying on Startup FIXED

I have had the engine dying on startup issue intermittently for like 6 months, slowly getting worse, up to 5-7 times per week on my 2019 M5C.

I collected numerous posts about this issue, spoke with mechanics and with you guys help, I was finally able to convince my dealer that the LOW PRESSURE PUMP was the likely culprit. They did diagnostics on it and surprise!....the low pressure pump showed multiple faults. They replaced it and what a difference. The car now starts strongly every single time over many starts. If you have this issue, get it done. We now know the fix. Thanks for your help.
