Do you have the 100uF series capacitor there on purpose? The output is now AC coupled and there exists a DC path through both LEDs to ground.
The two circled LED's alternate on and off. The 100uF causes them to not fully go off, but rather they get dimmer and brighter. It works really well for about a minute, then they both stop and are on, (no flashing).Do you have the 100uF series capacitor there on purpose?

Place a 10nF capacitor from Control to GND instead.
The Control pin sets the threshold of an internal comparator. Having it at 6V could cause problems as the timing is no longer standardized.

If it is an overheating problem, any ideas how to solve this?The 555 for some reason stops working and the output gets clamped to Hi or Lo. In either case, the 100 uF capacitor no longer plays any role. Both the led.s run off 9 volts with 440 Ohm resistor in series.
If the 555 is overheating, it will shut down.
Forget my second statement. It will not apply here.If it is an overheating problem, any ideas how to solve this?
