1997 Other Oldsmobile Models Trouble starting from time to t

Electrical problem
1997 Other Oldsmobile Models 6 cyl All Wheel Drive 130000 miles

The car will run fine for awhile and then die and not start. It cranks over just fine. It acks like its not getting a spark. It has a bank of circuit breakers and fuses under the hood on the passenger. The diagram of their purpose was suppose to be under the cover but I found no diagram. After it dies the electric windows won't work or the electric seats. I think a circuit breaker or relay opens and prevents current to flow or spark to occur. It is getting worse in dying more often and then not starting. It will crank just fine. There just does not seem to be any fire in the plugs. Your suggestion or where can I get a diagram of the circuit breakers and relays under the hood?
