Check and clean AIS motor. (automatic idle speed) sometimes referred to as IAC as well. ( Idle Air control) same thing. remove it and clean pintle (pointed end) well with throttle body spray cleaner, as well as port it comes out of, and try it. If it's cured great, if it happens again a little later, replace it.

Try holding key in start position while moving shifter slowly through all gears to see if you get a click or start at all. Safety neutral switch/back-up lights on transmission were known to cause that problem.

My 1988 Plymouth horizon had some gas put in it that was mixed with 2 cycle oil and then it was ran out of gas totally. I get some gas put in it and it has just spit and sputtered and been messed up ever...

What you have there sounds strange to say the least. The codes seem unrelated. (ignore 55...that is just the end of code string). Before going any further check every fuse and fuse socket to make sure everything is good there. Don't bother identifying the fuses just check them. ALL....ones under the dash AND the ones in the power distribution center. have you tested the MAP sensor both for vacuum and electrically? There are individual component tests you can do using a digital multi meter. Instructions are in chilton or haynes manuals. (manual and meter probably cost less than half what you've spent already). If you find nothing then you will need to "pin out" the wiring from the computer and make sure everything is getting to and from it properly and also Why not test that O2 sensor and make sure the converter isn't plugged? You can often clear the injectors by putting 4oz of acetone per 10 gallons of fuel into the gas tank. I can't write out instructions for all the tests but if it ran well before you added the chainsaw fuel (which normally does little or no permanent damage), you are probably missing something simple. I can't tell you what it is only because I can't see it!!!

When advancing down highway vehecle spits and sputters then clears up then spits and sputters what is it

When was last tune up? Plugs, wires, all filters & fluids? Especially fuel filter. I'd start there and run a good fuel system cleaner through it.

Truck runs like ****

You have checked the fuel pressure? Do you have a check engine light? As for the tank filling up the wrong one, that is caused from a bad tank select valve on the frame rail.

I would change the fuel filter and have the alternator tested and check the condition of the drivebelt
