92 integra losing all power help

[gachg1187]

hey i have a 1992 integra ls ...the other day when i was leaving to go to lunch my car stoped running just like you turned the switch off and somthing under the dash started clicking. When i went to crank the car there was no power just like you unhooked the battery so i check the cables and they were all tight.I got back in the car and it cranks up and didnt give me anymore problems. A couple days later i got in my car and fixing to leave and it did the same thing but this time it had power to start back up but it died every time for about 5 trys... can anyone help me out on this one

...Thanks Cody
