Hi all,

The above truck is in the shop now.  The complaint is an intermittent lose of power while pulling a car trailer.  If the customer pulls over, shuts the truck off, and restarts after 30 secs the problem goes away.  The only code that I had was a P0093 ( Fuel System Large Leak Detected).  I road tested the truck and was not able to get it to act up.  With the Tech 2 when I comand the fuel rail pressure I will not go over 16,000 PSI when the desired is 23,000 PSI.  When driven down the road the actual and desired are normal.  What could cause this?

Thanks
