Engine power decreases after few minutes of operating.

[sdw363]

I can start the engine and operates normal for a few minutes then it gradually decreases in power, from 100% to 90% to 80% and so on. Have changed fuel and air filters a couple fuel lines. Cleaned and flushed fuel tank and changed pickups. Any suggestions or recommendations I would really appreciate it. Thanks in advance.

By decrease in power do you mean you lose RPM ?

 

[Topper1]

More info needed on the circumstances around power, rpm, response loss. What is the machine actually doing?? Losing power? Rpm? Rough temps and situation would help a lot.
Could be almost anything without proper diagnostic description of events.

Does it have a ecm? Any codes? Run it till it looses power re prime the fuel system and see if there is any air in the system

After the bell rings a message appears (Eng Dehydrant) but no codes. The engine don't sound like the RPM is going down. Has no DEF.
