On my 180 mile trip today, at about mile 150 I lost all power.  Engine was still on, no warning light, and all engine specs within range.  I pulled over and called Frank McElroy who suggested a loss of turbo.  He was spot on.  Turbo pressure was zero.   But after a few minutes, turbo started to work.  I get back on the road, but after a few miles, turbo drops out again.  I was able to keep moving as long as I didn't try to push it.  I could even maintain 50 mph.
