Sounds like the check-valve on the fuel supply system. This keeps the line pressurized overnight or over a period of time. Try turning the car into the "on" position for 5 seconds before starting it so the fuel pump can pressurize the line. If this method fixes the problem then it's likely one of the check valves in the fuel supply system.

Are the plug wires original? If so replace those next.
After that I'd swap out the ignition coil. For my '98 that cost $80.

Could also be a vaccum leak as well.

Thanks all for the advice.
We've been waiting a few seconds before starting the car. I'm happy to say that in the past three weeks, the problem has only occured once when we didn't wait. I'm looking into replacing the fuel check-valve, but can't find it on my car. Would a fuel injector pressure regulator or fuel tank pressure sensor be the same thing?
The wires are original, but appear to be in good shape.
I hope it's not a vaccum leak as they are hard to find.
