Failing fuel pump is your best candidate without logical diagnosis. Less frequently a fuel filter.
Could check the pressure and flow rate at the fuel rail or replace the pump if it's years old. Do a filter soon too.
Get part number and shop using www.furiousmethod.com if you can DIY. Many vids on youtube.
Usually Bmaparts.com has great price.

Fuel, air and spark are your three troubleshooting friends.
