What are you driving, what mods do you have, done any recent work?
What scan tool did you use to pull codes, does it read live engine data?
Batteries fully charged, oil levels good, filters been changed recently?
You have to help us out - troubleshooting over the internet is a challenge even WITH this type of information. Without it, I suppose we could guess at an answer, but that can get costly.

P2290 (running code) on a 2003-2004.25 6.0L is most likely caused by, in order of likelihood:
1- Failing, cracked and leaking ICP sensor and oil damaged wiring at the sensor
2- A weak or failing High Pressure Oil Pump
3- IPR valve
This is a "running" operation code.
The codes can be from an actual mechanical failure (see list above) or even faulty programming.
Please pull and inspect the ICP sensor and the connector (pig tail).
Also, it would be helpful to see live engine data:
ICP pressure
ICP volts
IPR % duty cycle
When cranking, at low idle, and high idle
First on a cold engine, and then on a hot engine
