code 320

I have a 2000 Durango 4.7 liter and the check engine light came on at the same time the engine died. Managed to restart and get it home. Idles very rough and stalls frequently. I get a code 320
Ignition/Distributor engine speed input circuit malfuntion and
code 725 Engine speed input circuit malfuntion. Now what? Anybody know what parts need replacing or where to check from here. The dealer wants $85 to run on their computer which may or may not be more specific. [email protected]
Thanks.
