after 20 miles or so my engine stumbles bad, then dies and won't restart for hours. The check engine light comes on and displays the code 300 for multiple miss fires. I replaced the wires/ plugs/Ign. module/ and the crank shaft sensor. No change. What else is in this system to give me this code?

You going to have to do the testing when it doesn't start. Need to narrow down if it is lack of fuel or spark (most likely) or both. A spark tester and fuel pressure gauge may help to confirm.
