Hmm, usually your character loads up and enters the area long before you leave the loading screen. And it doesn't take very long to hit the ground, die, stay dead for 15 seconds and then zone to the DR.
I've been having the same problem as you, actually, and my character has around 150 health, except I load fast enough to actually see him die. Have you tried the alternate route inside? (Ask in-game for specific directions)
