e46 M3 - Dies at Idle / accelerating from a stop (intermittent) (SOLVED WITH UPDATE)

[AWE46M3]

Thanks for posting the solution in the update - super helpful. Just had big 3 done and got those sensors replaced. Fuel pump + relay is on the preventative maintenance list.

This is a classic fuel pump failure. It's good you changed the sensors but there would've been a code. This was the fuel pump as I've seen this happen on multiple BMWs.
