Take the battery out and take it to autozone or somewhere you can have it tested. It sounds almost like the battery is having trouble providing the power to the starter. If the battery tests fine put it back in and check all the connections to the starter and those coming off the battery to make sure none are corroded. Then check the fuse in the engine fuse block to make sure it's good and the fuses inside the passenger compartment. If everything looks good and it still won't start try the old fashioned way of putting a screwdriver across the starter to jump start it and see if it cranks if it doesn't then it might be a bad starter.
