If it's the same as my old LeBaron, the problem may be in the wiring to the power module. My was placed next to the battery in the air stream to the intake. Battery acid works its way into the connectors and kills the fuel pump and the power for the computer. If the power loss or check engine lamp doesn't light that may be the problem. I had a few corroded wires running to the fuel pump that ruined it. A year later the computer would wink out and sometines the car would not start for a little while. Cleaning and packing the connectors with silicone grease fixed it.
