Typically a battery lights boils down to an alternater problem, not always of course.

You need to pull codes to find the check engine light reason for illumination.

Check fuel pressure when the performance problem happens.

Maybe all three are related, maybe not. Concentrate on one at a time, with the possibility of a relationship of the other symptoms. I'd start by getting the codes from the pcm and seeing what it's seeing.

Suggested Repair

Retrieve the PCM trouble codes first. The battery light often indicates an alternator or charging-system problem, so test that next. When the power loss occurs, check fuel pressure, and address one symptom at a time in case they are related.

Conversation Summary

The owner of a high-mileage Ford Escort reports hard starting, an illuminated battery light and check engine light, and intermittent power loss after replacing the spark plug wires. The expert says the battery light commonly points to the alternator, recommends pulling PCM codes first, and checking fuel pressure when the performance problem happens.
