Jay, what kind of motor bro?   A big block Chevy approx 3/8", a small block Chevy like 1/4", dont know about the Ford stuff, but betting this is close...

A good way to test this is with a degree wheel on the crank and rotate the crank with a breaker bar, you should not see more than 2-3* of crank rotation before the rotor moves...May need to move it back and forth to get a good read.

Really Glen 
I had a timing chain once that resembled a bicycle chain.
I replaced it and my shut down issues went away.
As a side note, the new chain was tighter than a snare drum.

Clarification/disclaimer..........

I was assuming we were talking about a "broken in" deal, not new....That being said, a timing chain stretches like you can't believe, they can go from very tight to really loose in a very short amount of run time....

The knarlier the valve spring/cam, the more they stretch.....The degree wheel check is the tell tale...BTW, I never heard of a loose TC giving "shut down issues", only funky idle problems and torn up distributor gears.
