wont stay running

What is your question?

2000 Chevy Astro AWD Had to recharge battery after sitting this winter. Started right up first attempt. next day will turn over, but not stay running. Before sitting past winter, was having difficulty staying running, after a few miles would chug and eventually die and not restart. Would have a better chance at starting if I let it sit for a day after running. Any idea what this could be?
