6.0 New years hangover

Any ideas or direction to figure out this issue. 2003 F350 6.0 72,000 miles. Loss of power while climbing hills. This is the first problem since new. I have not been able to rescan yet. (can't find my buddy). Orig codes were(p0281, p0266, p0269, p0281,p0232). Fuel pump replacement resolved initial problem, drove for several weeks and problem returned) I have had this problem for the last (3) weeks. Engine starts up normally but idles rougher than normal. with a laser heat gun on each exhaust port it appears the right bank cylinders are not firing(or occasionally doing so) compared to the left bank cylinders. (RB approx 75-100 degrees, LB 250-300 degrees). Have done the following tests, repairs.
Replaced fuel pump/filters 50 psi(pump failed during testing orig scan codes)
Drained tank, refilled with different fuel, checked supply/return lines for restrictions up to engine fuel filter
Replaced air filter
Replaced both batteries
FICM voltage 48.2v minimum
Unplugged ICP sensor (to try to obtain default HPOP pressure) no change
On a separate question, I am getting ready to purchase an autoenginuity tester w/enhanced Ford software. any opinions regarding this product?
Thanks, hopefully everyone had a safe New Year.

I was reading a post on another site and on the 7.3 if a short is detected in the wiring harness the IDM will shut off a bank of injectors. Does anyone know if the 6.0 fuel management system will do the same??
