problem solved, one cable from sensor oil pressure in engine was disconnected, impco module after 35 sec stop engine, i saw this error but only when engine stop, when engine working there was no error
Check the voltage at the LP lockoff valve. see if the voltage is dropping before the truck dies. May be an overheat sensor.
when engine stop resound long sound, but oil pressure is ok because when engine stop in impco software show error pressure oil, clear error start engine oil pressure ok,
Sounds like a high temp or low oil pressure shut down.
