van will start after a day of sitting but will go dead in a minute or so and turn key and nothing will not turn over just click at relay

Is the battery light on ? Because it sounds like the alternator is not charging should be charging at 14 volts with vehicle running.

no light and does the same thing with two different batteries

Sounds like you have a short somewhere like a light that is staying on like the glove box or under hood light staying on or the headache one a motor shorting out like a window motor or something of that nature.

After re reading your question have the starter checked. Have someone tap on starter with a hammer while trying to start vehicle at the same time if vehicle starts replace starter. This is just one way of checking for a bad starter may work may not but it still can be the starter if does not start by tapping on starter.

after i let van set a day it will start but will start to run rough and then die after a minute or so
