What can I do to keep from having to jump start.

Diagnose the actual cause of the problem. What clues led you to the generator? Have you tested the battery? Has the charging system been load-tested?

Do you think the battery is any good? Another issue could be a battery drain, overnight? If there is a drain, you pull/replace fuses one at a time. When you pull the fuse on a faulty circuit, the excess drain goes away. The drain could be a light on, somewhere? Interior--under the hood--in the trunk. The old way to check for battery drain was to take a battery cable loose, use testlite between cable and battery post. If the lite comes on, you have a drain. When you pull fuse on the faulty circuit, the lite goes out.
