i have an 88 rx7 turbo. last little while i am getting random shut offs of the engine. for no reason it just dies. now when i try to restart it, i get a solenoid type clicking noise coming from under the drivers side of the dash.(almost sounds like a starter trying to turn over with a dead battery). slowly getting worse and worse. usually happens mostly when it rains out and less in better weather(seems that way anyway).
its not a dead battery. turns over fine when it runs good.
any help or suggestions would be appreciated.

if it helps. i can hit the rear defogger with the lights on and it will die. i can turn a corner and it will die. even if im accelerating, it can just die. ill wait a min or 2, turn it over and drive away. totally random. may happen 5 imes on a 10 min journey to the store or i can travel a few hours and upon returning home to my driveway, close my power window and boom...dead.
im kinda lost

thanks for some suggestions

 

Check the relay under the steering column location under the dash,see if it is loose.
