Mag FightFollow

So, I did Mag's Lair for the first time on Sunday and it seems like my pet died a lot in there. After the fight began, we were attacking the first cube guy and bam, pet's dead all of a sudden... we move on the the next cube and I res'd him and he stayed up until we had Mag to around 50% and died again, so I res'd him again (I was figuring it was better to stop DPS a little so I could have more DPS overall, I'm BM) and he stayed up that time until mag was at 3% or so.

I was hitting the heal button quite a bit, but just couldn't seem to keep him up for the fight. I have no idea what was wiping him so quickly with the first cube guy (we wiped once, and both times he was killed on the first cube, but none of the others)

I guess what I'm asking is, does anyone else have pet problems with this fight? And, what do other people do during this to keep their pet up?

I usually don't have any trouble with mag, So it's probably just a string of bad luck.
