Using 550EX as master and 430EX as slave.
Sometimes slave works and sometimes not working. Usually first 10 shots work perfect and then it does not work. Batteries are full.
Any thought?
Thanks in advance.

Indoors or out?

Can they "see" each other? Sometimes, if the line of sight isnt perfect, it will work sometimes and not other times.

Outdoor.
I did a couple of indoor and it worked pretty well now i am looking back.
I was in a range of within 10 feet. Does it matter?

Outdoors the IR signal is very unreliable. Grab some cheap radio triggers.

The red light in front of the flash blinks so i assume so.

That's just telling you its acting as a slave. Check the pilot light on the rear of the slave for capacitor status. It will be constant red if its ready to fire.

As someone else mentioned, IR is hit or miss outside in daylight. Its much better in the shade, but still not like indoors.

I have not checked it but i was shooting about every 30 seconds so it should full.
I will check next time when i shoot.

I hear pretty good things about Pocket Wizard. Is this what i am going to need?
Thanks for reply.

No, not necessarily. Depends on the type of batteries you were using and how much juice they had in their cells.
