06 chevy 2500hd running bad 6.0L
at different times it will start missing. At idle,1500 rpm whenever. When watching scanner it is missing on all cyl.like a bad circuit in the ecm. Sometimes it will run great. When it kills it starts right back up missing. When it acts up I have good fuel pressure. It does not fluxuate. Have changed plugs and wires and crank sensor. I have tried wiggle test and tapping everything and nothing changes. There are no codes. Have checked all the grounds. Even the one on the head.

With no codes to go by, it would be hard to say.
Misfire on all cylinders does not sound like an ECM.
Take a fuel sample.
Have the throttle bore and plate cleaned of carbon.
I assume that you mean as it is dying the fuel pressure is fine.

Throttle plates are clean fuel is clean. Acts like it is loosing spark or power to injectors. While it is missing the fuel pressure does not drop stays at 60-62lbs

HMMM. That is wierd. You would need to confirm exactly what is causing the misfire- like you said either spark or injector pulsing. Maybe you are loosing spark or pulse to one bank.
