Well, it does seem as if it could be fuel delivery related such as clogged fuel filter. I would think it would always display the problem if this were the case, however. It's only when highway driving?

 

Yes that is correct, only hwy driving. Ran the gas down to 1/4 tank & filled it with some 93 oct.
we will see tomorro.

 

Also, don't underestimate the effect of all that water on the plug wires. If one or more of the boots don't seal well, it could be getting some moisture in.
