Is your battery new? If the battery is new, the car could be starting and running solely on battery power and the alternator could be bad. 2 weeks after I bought my Q45, the alternator started acting up and soon after caught on fire. Use a voltmeter to check the alternator output if you can have someone start it while you're checking it. It should be between 13.5 and ~14 volts when the engine running. if you can start the car a bunch of times without battery dying than it probably isn't the alternator because once battery gets low it won't start anymore but its not a bad idea to atleast consider it.
