Help! X5 starts then stalls

[tMac]

Help! My 2003 X5 3.0 has been driving well through the years with hardly any problems. Yesterday, it started but after just 3-5 seconds the engine stalled, which has never happened before. I tried this a few more times with the same result. I plugged in OBD II but no errror codes show. This morning but while I can hear the starter firing, the engine would now not even start.

The only "odd" thing I recall doing before the last time I drove the X5 was accidentally hittting the steering adjust lever while driving. I've never had stalling problems with my X5, and the dash and lights are working. I still have not replaced the original batteries, but given the electricals seem to be working just fine, am doubting whether this is the issue.

Appreciate any thoughts from this forum.
