Under what conditions? I don't think that car was included in the GM ignition switch scandal but it could well be a faulty ignition switch. However it could be a lot of things and more details are needed, in particular any current, pending, or historical codes that the vehicle may have stored.

keep going completely dead

Can you please explain what this means? I don't know if the car won't start, or it stalls while driving, or what ....

Please list all the symptoms, conditions in which the problems occurs, and troubleshooting you've tried.  Please give as much detail about the problem you can, and full vehicle details, please, because this isn't nearly enough to even start helping you. Thanks.
