FIXED! 93 F150 sputters in drive. #17 fuse blowing

I have a 93 F-150 v6 4.9L 2wd with 80k miles. Recently it began stuttering in drive, not making into 2nd gear. It is a consistent "shot" of gas then nothing. Again and again. If I shift down into 1st or 2nd is seems ok. If I have it in park and press the gas it will rev up the engine fine. It only happens in drive. I had the same issue 2 years ago and had the fuel pump replace by mistake. It turned out to be the ECM so i had that replaced and it worked
afterwards until now. I assumed it was the ECM
again and had it replace with no luck. The check engine light is not on and I get 111 when I pull codes.
Any suggests?

*FIXED
$#@%!....after lots of research and little help I have find the issue. #17 fuse kept blowing due to a short in the O/D switch. The **** at the end of the shifter had loosened over time and was blowing a fuse that in turn stop the truck from shifting properly.

Do you have a fuel pressure gauge?

Key on engine off it goes up to 50 psi and slowly decreases. Engine on is a steady 48 psi. When I removed the hose to the fuel pressure regulator it increases to 56 psi.

So after further digging I found a blown fuse. (I feel like an idiot). It is fuse #17, I replaced it and it worked fine for about 5 minutes and blow the fuse again. Most of the info I find onine says it is caused by a wire shorting out and blowing the fuse. The problem is I don't know where to start.
Any suggestions?

Look up what all the fuse controls, if you do not have one, buy a haynes manual and look up the wiring and trace it out. Either a wire is broke/chafed and it will continue to have problems.

Haynes manuals can be had from just about any auto parts store and are invaluable. Every time I buy a vehicle, I get a Haynes manual for it. When I sell it, the manual goes with it.

Yep. Spot on. I prefer Factory manual when I buy a new vehicle. But that was 19 years ago. LOL. So Haynes is great. Whenever I replace a electronic component I do a wire check. Amazing how the insulation just begins to crumble.

After tracing every wire I could possibly find I still have not found a short to ground. I have search every forum and it seems that one of the most common places for the short is the O/D wire in the steering column. Mine has no worn places but I notice if I *unplug it the fuse does not blow. Is this the problem?

*picture is the plug from shifter O/D

It was the O/D button causing the short. The **** at the end of the shifter had rotated over time causing the fuse to blow. There were no visible shorts in any wires
