My 1990 Caravan LE just started dieing today.  The engine just shuts off.
If I select Park, turn the key completely off and restart it will start
right up for a bit.  Then it will just shut off randomly.  I can go anywhere
from 10 miles to 5 feet.  Doesn't matter.  The fuel pump was replaced about
5 years ago.  Could it be the fuel pump relay?  I purchased a new one for
$12.00 but I cannot find where it goes.  Both my Chiltons and Haynes manuals
don't list it anywhere.

Any ideas on this?  It was running warm for a few days but I just replaced
the radiator and t-stat today.  Temp is on the cool side now.  :)  Now it
kills.  AUGH.
