So misfire only on hot soak restart for a short time. Coil would be my thought too. Possibly a leaky injector flooding a cylinder and once the fuel clears up, no more problems. Hot and throttle snap fuel pressure is also suspect, as @Schurkey mentioned.
Do scan tools offer mis counters on obd1? I mean it’ll be helpful regardless to monitor mixtures and inputs, maybe WOT O2, and coolant temp during hot restart but you have some other diag avenues still.
