Default no spark sometimes?

My car has the ability to start and run great and then hours won't start at all. I know it'* a spark problem from testing it. has anyone run into something like this before? I've already dropped 400 bucks replacing everything I could think of. And I don't have the money to take it somewhere from them to to try 5 different things. I really love this car please help....

Give us a list of everything you've already replaced, and which cylinders are missing. All? Some? One? Random? And have you pulled PCM codes? What year and trim level of Bonneville do you have? SE? SLE? SSE? SSEi? Put that in your signature

my first thought would be ICM or spark modules... more common on the 87-92 tho...so yeah, what have you replaced?
