It is very weird but my bookmark to the linked page works fine the link is not working from this website. Try copying it and pasting it in a new browser. Copy Paste did not work for me. I noticed that the pasted version was pasted here to read different than what I copied I guess the website prevents certain links. Anayway I rewrote it to be correct so now you can copy it and paste it in another browser.
Here's the input link:

http://www.dakota-truck.net/CODES/codes.html

Your link still goes to the CGI link, which doesn't work.

(Why, yes, it's in my bookmarks, why do you ask? *grins*)

Did you also get a 55?

If not, you didn't count the pulses correctly.

If you DID, those two are:

Code Description
46 Battery voltage sense input above target charging voltage during engine operation. (voltage too high) ***
52 A rich air/fuel mixture has been indicated by an abnormally lean correction factor. **

So, I'd check the charging system voltage first; do you have a voltage gauge, and about where is it? (Or even better, check the voltage.)

Again, if you DIDN'T get a 55, then try reading the codes again. You will always get a 55.

I think I read the codes wrong. If I read right, the first code was 46, which says charging system voltage too low. I had the battery, starter and alternator tested afternoon. The battery has 12.57 volts, rated at 690 CCA but has 801 CCA. The starter showed 11.27 volts at cranking with a time of 3.80 seconds. The charging system showed no problems with no load on it at 14.02 volts and charging system loaded at 13.92 volts.

I think you misread the code list Josh.
46- Battery voltage sense input above target charging voltage during engine operation. (voltage too high) ***
52- A rich air/fuel mixture has been indicated by an abnormally lean correction factor. **

Ralph, I think I copied a link after I searched the number as that shows up CGI on the address bar.

This morning on the way to work, I started the truck up and let it warm up for about 10 minutes before driving. About two miles from my house, while sitting at a red light, the truck shuts off with me. It acted & sounded like it wasn't getting fuel. The gas gauge read half-way between 1/2 a tank & 3/4 a tank full. I fired it back up & ran fine. Parked it at work, & before I shut it off, I noticed it idled smooth & perfect.
Keep in mind, I changed plugs, wires, rotor button, cap, fuel filter, and have changed air filters several times since last October.
Any ideas?

You did, but the message still links to the CGI page, alas.

Check fuel pressure.

A fuel pump that's failing may cut out and then start again without any notice; and if you're low on pressure to begin with, it won't take much to kill the motor.

I recorded a video of me doing the trouble codes. I posted on a Dodge Dakota 1st gen Facebook page. Two people said my truck was showing codes: 13, 15, & 52
Code 13: MAP sensor
Code 15: Vehicle Speed Sensor
Code 52: running rich

Does your speedometer work?

Fix the map code first, and see if the 52 goes away.
