Try removing the battery cables and cleaning them....as well as cleaning the terminal posts on the battery.
The reinstall the cables and try again.

If you have a voltmeter, you might try checking the battery voltage when the ignition key is in the "ON" position....just in case the battery is failing under load.

Then, check the ground connections where they connect to the engine block and the body.
