Rough idle at startup and cuts out when attempting to accelerate

1996 Ford F350 XLT Powerstroke 7.3 rough idle at startup and cuts out when attempting to accelerate. After warming up for 10 minutes or more the idle will get smooth and seemingly normal. After warmed up the engine can be accelerated to operational rpms for a few seconds then it will cut out abruptly. When brought back to idle it will idle very rough again for 20 or 30 seconds and go back to normal idle like flipping a switch. Since this issue began the engine is currently losing 3 quarts of oil in approximately 150 miles.

This issue initially began as a popcorn popping type of backfire and miss upon acceleration.

Recent new parts:

Fuel pump
alternator
Fuel IPR
Exhaust EBP
Camshaft position sensor

Fuel tank and filter are clean.

Is this an injector issue, fuel delivery or electrical? If someone could please suggest what to look at I would greatly appreciate it.

welcome to PSN.
first thing i would check for is burnt pins in the valve cover harness.
is the check engine light on?

If you want the moral high ground, make sure you're not standing on a hill of horsecrap.
