If it wasn't for the codes I'd say O2.

The starting problem sounds like its in the Neutral Sense circuit. Start with the switch and go from there.

EGR codes might be the flow sensor, might be a leaky valve.

I would replace the O2. My guess is that the O2 sensor is producing a false signal that doesn't trip a code. Computers aren't perfect, and neither are sensors. They can fail in ways that won't trip a code. that is why you have to be smarter then what you are working on Taking a volt meter to the O2 sensor will tell you for sure. Wait until it gets warm and goes into closed loop. Watch the voltage when you give it throttle or load, if the voltage doesn't move, or spike or anything you might have a problem. Of course cleaning grounds and such never hurt anything either.

edit: another thought. check the throttle position sensor. it should read around 0 for closed throttle and somewhere between 3-5 for open. The more important thing is that it's a smooth transition as you open the throttle. Or the map sensor in a similar fashion

ok this is just another hint may or may not be problem but on my 05 f250 i would get high rpms and no power run like crap throw all kinds of codes and what it end up being was the screen on the fuel pump was so cloged up with crap would get fuel then it would not I removed screen and that was a big mistake truck would not run at all put new way too damn costly fuel pump in run like new hope this helps

remember this is a 93 4.0 with MAS air and dual O2 sensors. I have a Air/Fuel O2 meter sitting on my shelf that I think I might throw on just for fun.

TPS voltage is .95 at close with a smooth trip to 4.5 -TPS and MAS sensor were both replaced.
I am thinking of dropping the tank and cleaning it just to make sure that the fuel pump screen is not plugged or blocked. Has new fuel filter also.
bought a fuel pressure gauge today so I can do the KOEO fuel pressure test and the running one.

ran new vacuum line from EGR purge solenoid to EVAP cannister.

Opened my new Fuel Pressure Gauge. Fuel pressure KOEO fuel pressure was 38psi, steady state 32PSI and goes up to 39PSI as soon as you hit the gas. So that is not the issue. Vacuum steady state is 18 in.

Big thing I noticed after doing all the Grounds correctly and redoing the positive cable was that the charge voltage shot up to 16volts. Drove it around the farm again for a while charging the battery. Now the hesitation dieing is gone!

Idle is now 1000 rpm and it runs great! Lots of power down to 1500rpm and up to 5500. Had all 4 wheels spinning in a mud puddle

SO STOKED! :

So final analysis may be that battery voltage was not where it needed to be and then the computer needed to relearn everything after proper grounding was done.

next up is smog test and title transfer

do the o2 sensor seriously everything sounds identical to what mine was experiencing i would fix one thing and it would seem to work good but then i would notice it about 15-30 mins after driving it.

about what I said =(
ran another ground from battery to frame. going to add a air/fuel ratio gauge tomorrow if I have time.
have to watch and see if the voltage meter goes to 0 also next time. doesn't seem to affect the starting circuit. so it is in the electrical or fuel circuit. Need to start reading the electrical diagrams
