2005 Ford Focus Electrical/Alarm Glitch

Electrical problem
2005 Ford Focus Engine Size unknown Wheel Drive Type unknown Automatic 41000 miles

Over the past few weeks, we've had an electrical glitch that caused the dash lights to flicker, and radio lights/sound to go in and out. The car would also lose power timed with the flickering. This evening while driving, the alarm, which we thought was disabled, came on and shut the car off. It will not restart, and the alarm goes off with any provocation. We live over an hour away from my husbands work, so while the car is out of commission, so is he - please help asap!
