If the car starts when it is cold or not warmed up and then doesn't when it is warmed up or hot (like when you stop at the store and then get back in), it is one or both of the Battery Cables. When cold, there is enough voltage through the battery cable to energize the starter. When it is warmed up and restarted, the engine heat causes additional resistance in the battery cable to limit the voltage to the starter and not allow it to start.
There is a Relay in the Fuse Box by the Battery that allows the Fuel Pump to energize when you start the car. Sometimes the relay fails and maintains a connection to the Fuel Pump, which drains the Battery after you turn the car off.
This car is 30-years old and has been exposed to significant degradation. Also, there are wires on the Fuel Pump, which is submerged inside the Gas Tank. Over time, these wires become corroded and must be replaced. No matter what you find to be the actual problem, you should consider replacing the In-Tank Fuel Pump and attached wiring.
