Someone recently pointed out a place that makes up a hose and gauge, and looked like a good setup ready to go.

Yes there is, I was driving in first gear / 4th and I could feel the tractor slowing down going over a bump in the dirt.

Guys we got it. It turned out the be the check ball in the return line fitting that goes into the inj pump. The ball was stuck with some debris, cleaned it and BAM !!! she came alive like her old self. That check ball looked a little odd almost like it was a clear plastic ball in the fitting. I just want to thank all of you for your input and patience, what I learned here I will keep for ever......

I'm glad you determined your problem. Normally plugging of check ball in return line indicates drive coupler in inj pump is deteriorating and pump will require repair. Engine may run fine for a while BUT be aware that it's possible for engine to over speed IE run away sometime in the future.
