Taking a guess, Your 1988 5th Ave has a 318ci motor with Lean-Burn Engine control. Chrysler put the control module in the rectangle box attached to the side of the air cleaner. All of the engine control module is inside that box to include the transistorized ignition system. Your distributor will have two pickup coils in it and not have a vacumn advance located on the side of it which will be another way of telling if you have the Lean-Burn system.
There is no ignition module on a 1987 5th ave. The spark control computer is on the air cleaner with a vacuum line hooked to it.
fuel pumps about to go out -or more likely your electronic control module is failing.
Behind the battery
Have you had the alternator tested? It may not be regulating the energy to the battery, causing it to drain
