why does my ignition not read all the time? on 1991 Acura Legend

sometimes when i try and start her up, the ignition sensor or whatever it is does not read properly and she wont start up. I than have to unplugg the negative from the battery to let it reset. This is the best that i canexplain this problem. how can i fix this?

in the column behind the key and tumbler assm there is a plastic ign switch that at times goes bad and will cause starting problems ,start there
