Hi Gene,
I am not a fan of ARCO gas as I have had issues with our Royale running on that gas even though it ran fine on other brands. No explanation as to why, but I think you will find the module or the coil will be the bad guy here.

Thanks Jim, Roy, and Armand,
The Arco is a high volume station located next to the Home Depot and Holiday in Express. I only mentioned that it was Arco because some people say
their gas is low quality. I drive the GMC a lot so there is never old gas in my tanks. I had just emptied the tanks so I could drop the rear to
replace lines. I re-filled immediately before the each trip up the hills.
I checked the plugs yesterday. All were burning clean- light tan to whitish color. Maybe too lean? Gaps were beyond .055- re-gapped to .045 as Jim
suggested.
No.1 plug wire had been living too close to the header- had a hot spot with small crack and appeared to be leaking electricity. Taped it up and
relocated it away from header.
Took test drive over Fredonyer Summit (5751 ele. East bound trip had no issue. Coming back up the other side I had the starvation symptoms again. Not
as extreme as before but still very noticeable.
