[W126 Coupe] !988 560 SEC

[Dan Stratton]

Have you replaced the fuel filter? I'd try that first, before spending a lot of money and time on the other stuff. I've been through that before (same problem) on a rarely driven '87 420 SEL (22K miles) - in the end all that it was was the fuel filter.

I am also having a "cutting out" problem. On a 350 mile trip last fall, my  
SEC would lose power after every 1hour and 45 minutes.  I would have to  
pull over and turn off the motor for a few minutes, then it would start and be 
good for another 1-3/4 hours and lose power again.  I finally got to a  
dealer and picked up a new 'fuel relay'.  This got me around while visiting  
and all the way home again...I thought all was good.  Last week while on a  2 
hour drive, it lost power again at the 1-3/4 time period.  Could this  just 
be a new fuel relay gone bad?  What other part would "time" itself  out.  
Could the EZL or ignition module be the culprit.
