Hello to all, I'm new to this Forum but do have some experience (limited) with Disco's. I have a 1997 Disco with 118K. When I'm driving and get above approx 50mph I will intermitently lose all power for 1-2 seconds. Doesn't seem to be any rhyme or reason. Typically happens more on the freeway. Engine just stops, then fires back up, pretty scarey.
I have done the following and have been informed by a Disco "Guru" that I should look for moisture in the camshaft position sensor or replace. Any advice on investigating will be helpful.

Spark plugs fairly new and look good
Spark plug wires the same
New fuel filter
New VSS (made the speedo accurate but no change in problem)
I have approx 38 psi at the fuel rail
I think this Disco sat for a while. I added a can of BG44 no difference.
Thanks for the help
