Sputtering & loss of power after good long warm up
Starts & idles fine & runs fine for 30 to 60 miles then it loses power & starts kicking & bucking but will still idle fine. let it cool off and it starts all over again with the same symptons? It is not running hot. Anyone got any ideas?

Sounds like it could have a stopped up catalytic converter, on way to tell for sure is when it loses power check the exhaust coming out if there is little air flow it is stopped up and simply can't breathe,
may look good but that means nothing if electrode in any spark plug go's op[en circuit when warm it will spluter as it will be mis fireing on that cylimber try a new set of plugs then check leads then distributor or electro ignition
Before you start buying new parts, I have two suggestions. First, have the computer scanned for diagnostic trouble codes. Any fault codes that relate to your problem should be investigated.
Second, spend the money for a compression test of the engine. What you are describing could very well be a bad exhaust valve that leaks and causes high gas consumption, loss of power, poor idle, etc. A compression test will verify if there is such a problem, or not. And, if it turns out that compression is good and high and even in all cylinders, you will have peace of mind knowing the internal condition of your engine is fine, and you will have no problem with putting money in it to get it running right again.
When your engine is running lean that means it's not getting enough fuel.So if it's one side (or bank) of the motor then possibly you have an injector problem on that side.You'll want to get a fuel pressure test to see if the fuel system pressure is up to specifications.Then get the injectors tested.These tests are simple and realitivly cheap.
I'm having the same problem with my 90 2.3L Ranger. I replaced the EGR Valve back in August and the truck ran fine (but the gas mileage was bad) until late December . I knew it needed an O2 Sensor back in August but didn't replace it until last Saturday along with the Idle Air Control Valve, Plugs and Wires. The truck ran fine for a couple minutes then started running like a VW bug! My code reader is now throwing out an EGR failure code, so I guess i'll take the 4 month EGR back and get a new one, and see what that does!
