1999 Dodge 1500 318 automatic, 382K+ miles. I live in Texas, but am clearing out an estate in metro Detroit. On the way from Texas to Michigan, the truck stalled while doing about 60 mph on an interstate. When I pulled over, I didn't see anything wrong under the hood, so I put on the spark tester to see if it had spark. When I turned the ignition key, it actually started. It gave me no such problems the rest of the way. A day after I arrived, it stalled in the driveway, and after not stalling for a week, it stalled 3 times since. It's always restarted after I put it in park, but never in neutral; it previously only stalled when the engine was warmed up, but this morning, it stalled just after I left the driveway.
Something is going wrong, but I don't know what. I looked at the various relays under the hood; they're all clean. I cleaned the battery terminals over the winter, and they also look good; the connections are tight, and I don't see corrosion. Last year, after a breakdown, the cap, rotor, and coil were replaced. The only maintenance I did before this trip was change the oil & filter. Local suggestions include a frayed wire, a bad ground, the fuel pump, dirt or water in the gas tank, the alternator, and the MAP sensor.
The problem is intermittent, and so far, there's no pattern. The Check Engine light isn't on, and a parts store OBD II tester returned no codes. What seems likely wrong with the truck, and what should I do to diagnose it?
