1999 Acura Integra

Few possibilities here.

Could be a loose power connection somewhere. Have you popped the head and made sure your battery terminals and cables are all fastened properly? Was the battery light on before it died or anything?

I have seen some failed ignition switches on your vehicle as well. But first I would check your connections, fuses, etc. Do the basics first. Check the voltage of the battery, make sure that starter wire is still tight with no corrosion, etc.
