Default 2000 Dodge dakota V6 stalling with "no bus" error

I have a 2000 Dodge Dakota 3.9L V6 that randomly stalls at random times, it can make it a few cities over or doesn't leave the block before stalling and turning off. The gauges would read their last input then fall like you took turned the key off and removed it. After a few minutes it turns back on with no issue until the next stall. There hasn't been any signs of electrical issues, radio works fine, windows work, battery seems fine nor any misfires. I've been too anxious to drive it anywhere out of city limits in the worries of it stalling. I have checked fluids and for lose wires and haven't found any. I haven't fully checked the PCM or any sensors but I'm not sure how to check or what i'd be looking for. Cannot afford to take it to a mechanic, need help figuring it out or ideas of what to check.

Need to plug in with a scanner, see if there are any codes...... also see if the PCM loses communication when the engine stalls......

I haven't seen any codes using a scanner. How would I check the PCM?

Will the scanner still talk to the PCM when the problem presents itself?

From when it last happened and I had the scanner on me yes, It's random so I can't per-say really check it untill it stalls next

So *probably* something else is going wonky.... causing the stall.... Can you do data logging?

Record sensor data while you are driving...... You have something going out of spec there, that apparently isn't setting a code...... so, being able to see what the PCM is seeing, is sometimes (but, not always....) helpful.

After testing things out, Strapping the pcm cables down with zipties to hold it in as a test. Didn't prevent a stall but now there's a check engine light with the fuel light lit up whenever it stalls. . Now right before it is able to start again it has a check gauges light then it starts right up. I have a hunch its the crank shaft sensor but I'm not 100% The code reader I had doesnt work when the engine is not running so I can't get a code when it stalls.
