Well...your battery is dead. Check the connections of the cables on the battery posts to make sure they are tight and clean (no corrosion). While you're under the hood, look at the belt (serpentine) that runs your alternator. Is it there? If it fell off, your alternator can't charge your battery. You may have a bad alternator, a bad battery, or no belt....but use a battery charger to charge the battery...your alternator is only designed to "maintain" the charge, not bring it up to full power. Good luck, alternators for the MX5 are spendy, so I hope it's one of the other problems.

Yet another problem I can't figure out can someone please tell me what it might be??

Check the battery voltage when the engine is running. You are looking for 13.6v or more, (up to 14.5v). Possibly an issue with the alternator wiring and not the alternator at all.

First start to check for fuel pressure. It sounds like you have a bum fuel fuel pump. Have some one turn the key and someone else listen nearest the tank to see if they can hear it turn on. Let me know what you find.

Battery is dead... get a volt meter, jump the car and with the car running on its own power check the voltage, anything less than 12v could point to an alternator but a new battery is a better place to start. put it to you this way if the car shuts off while driving, then its your alt, and if its fine wen drivin but wont start back up... its all battery
