Engine Performance problem
1991 Dodge Dakota V8 Four Wheel Drive Automatic 61000 miles

I have a 91 Dodge Dakota LE, 5.2 L that is stalling intermittently. Sometimes it will go several days without stalling. It will stall 3 to 5 times in the first few miles. I can be traveling 35mph or just parked, it does not matter. It’s just as if I turned the key off. Sometimes it will start right back up when I crank it and sometimes it will not. If it does not start, I can wait 45 seconds and then it will start right away. I hooked up a dwell meter to the coil and found that when it will not start the meter is just like the key was off but as soon as the meter jumps the engine will start within 2 seconds. Plugs and wires look fine, replaced the rotor, battery connections have been cleaned and are tight.
Any ideas? Thanks.

Check for codes
suspect and check ASD relay

I checked the ASD relay. The contacts looked good and the coil checked out at about 72 Ohms.
I replaced the relay anyway but the truck still stalls, no change.

The only engine code was 55. I think this code just means its the end of the codes. Right?

For the Hall sensor I uplugged it and tried to do resistance checks between the leads but could not get any values, probably because I have a digital multimeter. The diode setting did not give consistent readings.

With the sensor unplugged I did take voltage readings at the plug leading back to the engine controller with the key in on position. The wires from the senor are not color coded and the plugs did not have any labels either so I " m not sure which pin is what but here are the readings and for lack of any better labels I will label the pins top, middle and bottom: Top: 5v Middle: 9.1 V Bottom: 0 v. In all cases one lead of the meter was attached to chassis ground.

I did tap into the wiring from the sensor at the plug and monitored the voltage readings with the key on and engine stopped and also with the engine running. I tried to take reading while cranking the engine but could not get consistant readings, (the meter only updates about once per second so that might have been part of the problem)

Using the same labels as above, here are the readings: Key on, engine stopped
Top: either less than.1v or about 4.9 v
Middle: 9.1 v
Bottom: 0 v

With engine running
Top: between 2.5 to 2.6 v
Middle: 9.1 v
Bottom: 0 v
I left the meter attached to the Top pin as I traveled down the road and it was consistant at 2.5 to 2.6 v and I did not notice any changes just before any of the times the engine died.
If there is still some possibility of the hall sensor being bad let me know and I will get a new one ordered.

The truck did something new today when I first started it. It started and then died within a few seconds. It did this about 5 times and then I noticed the check engine light flashing so I checked the codes and found 32 and 42. After that it started and ran for a while but still did its usual thing of dieing 4 or 5 times within the first 3 miles and then running ok after that.
