That was my first thought as well. This setup has a Crankshaft Position Sensor built right into it. And with issues related to heat, these sensors and the Ignition Module that the sensor goes right into are usually the first thing to go. To check it you would have to get it to stall and then jump out and check if it had any spark coming from the Ignition coils. It's possible to do, since you have about a half hour before it will start again. But with the age of the vehicle, checking for spark when the stalling occurred would be the first thing, I would do to diagnose this.
With this system, in the second diagram below you'll notice in purple, those are the Ignition Coil towers, and because this is a waste spark system, if you take the spark plug wires off two or those towers, and crank the engine over, you should have spark jumping from 1 tower to the other. The spark will jump marked in Green from the number 1 tower to the number 4 tower. Just make sure you remember which spark plug wire goes on the correct tower it came off of. But the spark should be strong enough to jump that gap between the two towers, but keep your hands away, just crank the engine and watch with the hood open. If it's an issue with the Crankshaft position sensor or that Ignition module you won't have any Spark.
This is the first check I would do, but my concern would be that you said it starts right back up, so it might be that the Ignition Module is on its way to failing, it just hasn't failed completely yet. Since it starts back up, you are still getting spark, and then putting the vehicle back in drive puts a load on the engine and it might be that the spark is weak at that point, you can still try the test. If it doesn't jump between the two towers, then it's an Ignition Module issue. If it does and appears to be a strong spark, then it may be something else is failing. Fuel pressure would have to be checked next during the stall condition.
