I've got a 99 4X4 dakota with the 318. It has been randomly shutting off when driving. The first three times where when I was coming to a stop, and doing probably 20mph. The last time I was doing 50mph, and it shut off, and I coasted to a stop. When I start it up again, there are no problems, and I can go for a week or so before it happens again. There are no error lights on, and everything seems to be normal. I took it to the dealer and they did a throttle body service, and checked it on the computer and everything appears fine. Any ideas as to where I can check?

Thanks

Mine did that but it also would chug everyso often and couldnt get above 50mph. Turned out the crankshaft sensor was fubared.

 

I had that exact problem with a minivan a long time ago. I troubleshot it myself and narrowed it down
to what I thought was an intermittant spark module. -It wasn't-. I should have troubleshot it further.

It ended up to be a connector inside the distributer. There was a loose wire/pin in the connector that expanded/contracted with temp and caused the engine to die ( mostly at highway speeds).
I would coast to a stop, start it back up and it would run fine for a while and do it again. Sometimes I
could restart it while coasting to the side of the road.

Took me a couple of months to find that one. It ran fine after that, till I got rid of the van.
