1991 Toyota Previa - What next?

Toyota Previa 1991
While driving after a short period (when it gets warm) it stops and I have to wait 20 minutes to drive again. 300.000 miles!
When I can’t start it there is no spark or fuel both shut down. So far I have installed a new ignition coil, new spark plug wires, new thermostat. Could it be a temp sensor. What component would cause my problem?

Ignition control module maybe… shouldn’t kill the fuel though. ECU would kill the fuel and it is 28 years old. Old electronics die with simple age. This one has age and miles.
