If you can catch it failing again, test for power on the small wire going to the starter solenoid while someone tries to crank it. If you have no power, check for power at starter relay and trace backwards. If you have power, you have a bad starter. They can have intermittent failures. Hopefully your starter is easy to access, some 3 series and 5 series have the starter mounted under the intake manifold and it is necessary to removed the maifold to replace or test the starter. Good luck, hope this helps.
