555 Problem - New

As described previously, I have my first 555 project, a LED flasher that
looks like

http://ourworld.compuserve.com/homepages/Bill_Bowden/555.htm (The one
with
the 9V battery shown)

I have found numerous examples of the same circuit around the net...but
this one looks the clearest.

I have C as 100uF, R1 as 1K and R2 as 22K. Using the calculator, that
should have the LED flashing on and off for about 1.5 seconds each state.

The LED is set to draw 10mA on 9V

I got some solid core wire and was able to get things running....sort of.

Using that diagram above, I have one LED/resistor connected from pin 3 to
(+) and the other from pin 3 to (-).

When I hit the juice, the two lights alternate on and off as expected at
about 1.5 second intervals. However, after a few minutes the lights stop
flashing and the LED connected to (+) remains solid on.

If I remove the LED to (-). The other LED blinks for a while then goes
steady on. If I put the (-) one back and remove the one connected to (+)
it too blinks for a while then goes to solid on.

Any ideas?
