So my question is: is there a correlation between the MAP / BAR sensor and ICP, the ICP was tested and is operating properly.
As for as further Diagnostics what is my next step, I am currently logging any PIDs so that I can review them if it stumbles again
No, not directly. The MAP and BP are used by the PCM to control fuel quantity, timing and control, and VGT (plus a few other functions). However, from the 6.0l Powerstroke Manual 2003.25 page 115,
• The primary function of the ICP sensor is to provide a feedback signal to the PCM indicating ICP.
• The PCM monitors ICP as the engine is operating to modulate the IPR. This is a closed loop function which means the PCM continously monitors and adjusts for ideal ICP determined by conditions such as load, speed, and temperature.
• The PCM monitors the ICP signal to determine if the performance of the hydraulic system is satisfactory.
• During engine operation, if the PCM recognizes that the ICP signal is lower or higher than the value the IPR is trying to achieve the PCM will set a Diagnostic Trouble Code (DTC)  and illuminate the amber malfunction indicator lamp on the dash.
• The ICP signal from the PCM is one of the signals the FICM uses to command the correct injection timing.
The MAF sensor outputs an analog voltage signal to the PCM proportional to the air mass. This directly affects the commanded IPR position. As well, the AP (Accelerator Pedal) has a major affect on the commanded IPR position from a PCM signal.
You next step is to see what the IPR is doing when the problems are happening. The code 2290 is a maintenance trigger to look at the HPO system for a leak. It is possible you are in the early/intermittent stage of a HPO problem.
