"Service engine soon"light and stop engine lighta, 2002 bluebird, Cummins 24v.
Does anyone know what these two lights mean when they come on together?
I have recently had the bus sitting for about 6 months. It's sat with a full tank of fuel with one bottle of power service diesel fuel stabilizer mixed in. This weekend I head out from the property where the bus was parked on a 700 mi trip down to Florida. About halfway through I stopped for fuel and topped off the tank with diesel. Almost immediately after this fill up I had the service engine soon light come on and the bus lost power. Typically I see 20 lb of boost and 1100 degrees Fahrenheit EGT if I hold the pedal all the way down. With the service engine soon light on I would only get 8 to 10 lb of boost, EGT of 900° Max and the bus would struggle to go over 55 mph.
I pulled over shut off the bus waited about 5 minutes and started it back up. The light was off but came back on as soon as I accelerated. Within about 15 miles of driving with the service engine soon light and reduced power the red stop engine warning light came on. I was on the interstate and could not pull over for about 2 mi. When I did I checked both of my fuel filters and though not perfectly clean they didn't appear clogged. I drained off the water separator on the engine and the water separator on the filter underneath the body. This made no change and both the service engine soon light and stop engine light we're coming on intermittently. It appeared that the "stop engine light" would come on if I held the throttle all the way down though at this point the bus was struggling to go even 40 mph.
I pulled into a O'Riley's service shop and purchased a brand new filter WIX 33411 and water separator type Wix WIX 33585XE.
It seemed to help, though when I got back on the interstate and accelerated to 60 mph the service engine light came back on, the bus slowly lost power, and at this point the stop engine red light comes back on intermittently. The replacement of both filters appears to have made only a short term difference.
Any ideas what is going on here? It really feels like this issue is related to fuel and throttle application.
If I reduce my speed to 25 mph all the lights go off. When the bus is idling all the lights go off. Here is a video link showing the behavior of the bus.

I have a manual oil pressure gauge that shows that I have proper oil pressure 40 to 80 psi. I checked my coolant level before departing for the trip but I'm unable to check it now because I have a bike on a rack in front of the grill.
All help is appreciated, I am currently stranded at a cracker barrel parking lot near Savannah Georgia until I can figure out what's going on with my bus. I do not feel comfortable on the interstate because I cannot maintain interstate speed, and I fear that I may damage my vp44 if there is a genuine fuel delivery issue that I need to address asap.
