Such a symptom is almost always electrical.
If it were a hot engine only problem, I would suspect the Cam Position Sensor.
Corrosion in the wiring to the ignition is often found in the wiring from the battery to the AUX power box behind it. Best to take the battery out, unbolt the box, and look under it.
Shorting from cracked wire insulation to the injectors and various sensors is a common complaint on the 95. Was a recall but you may not be able to get it now. If you see any bare wire, at least tape it up.
Take it to the Dealer - if you're rich!
