My rig had these identical symptoms and after I changed the electrical ignition switch
the symptoms seem to be gone. I don't see much mention of this cure, but it worked
for me. Now the problem is losing 10 qts oil in 7 miles. It's in a shop for pedestal o rings
and oil galley plugs. There is blow by so that may be my next $$$ job.
