As for the revving - I can rev it in neutral or park when its cold. I get no power and no revs above 1100 ish. I can nurse it forward and back just not above 10mph. Since I've had it (and it was running) I've noticed it will idle smooth, then suddenly rough idle, then smooth out again. Besides checking the air filter (which is clean and std paper cartridge) I was planning on getting some throttle body cleaner and making sure its not too gross up at the top end. Its consistently run colder than I would like according to the ultragauge - typically around 160-170. The hottest it ever got was 206 climbing out of the Phoenix valley. I have a new 180 tstat I plan on putting in on wrenching day.

You're losing fuel pressure. Replace the fuel sending unit. In the cargo area, under the carpet, remove the access panel and then open the fuel tank. Pull out the old sending unit, and insert a new one. It is possible to replace just the motor, but replacing the hoses can be tricky if you don't have the clamps and tool. They're ear clamps if I recall.
Thank you all for the guidance!

About ABS, my trucks both have the fuses pulled because ABS will kick in unexpectedly during slow turning situations, like in parking lots or at the edge of a cliff. This causes the trucks to keep rolling. In my cases, it only caused moments of terror. In other cases it has lead to accidents. I decided I will pump my own brakes and pulled fuses after multiple attempts to fix the problem. In my case, leaving ABS fuses pulled is probably safer on the road and off.
Congrats on solving the fuel pump issue.

Exciting life!
My theory is the magnets in the ABS sensors have weakened over the years. Not yet willing to spend on new ones to experiment. I could get it to work well by reseating the ABS sensors (only a millimeter or so), but would only last a drive or two. Slow sharp turns were the worst for causing the problem. Maybe affects early '90s Range Rovers or Defenders, but I haven't researched that.
