Hi Joseph, I'm going to send this one down to the 7.3L forum. The folks down there will be better able to help you with this one.

 

This could be Injector Pressure Regulator related. There is an IPR on the front driver side, down deep in the valley of the engine. Make sure the tin nut is on that, for a first test. Second, take a can of air and invert it - that's freeze spray. Cool the IPR off the next time this happens, to see if it has any effect. Ice works too, but canned air doesn't melt before you get a chance to use it.




Do you have any OBDII tools/gauges like AutoEnginuity, Torque Pro, Dash Command, or Scan Gauge II?
