Engine cuts out at highway speeds on a hot day

...... it was cutting out only 1 minute after I turned the vehicle on. I had left my driveway and got onto the main road and was accelerating; then the engine choked in/out a few times.

Just about the time the PCM was likely changing from open loop to closed loop, and collecting data from the OBD engine sensors.

Cutting out suggests a faulty OBD engine sensor, or wire harness/wire plug faults. The fuel pump either has the correct pressure, or not.

Wouldn't a faulty OBD engine sensor spit out a code? How many of these engine sensors are there and what are their functions?

I have shut the tailgate on a blanket before. It took me about 20 minutes to get the gate open again and I was swearing the whole time.

It depends on the sensor and possibly very itermittent mal-function or sensor variation will not trigger a permanent code.
 
The OBD sensors can often be far enough out of specification, or intermittently faulty enough to cause driveability issues, yet not set hard trouble codes.

ODB-II live data should show any discrepancies, or just replace any suspected weak sensors and call it preventative maintenance. I would rather replace parts in my garage on my own time than be stalled on the side of a dark road in the snow or rain and having to diagnose and replace a faulty sensor.

I've driven so many hours with that OBDII meter installed, but the darn thing wouldn't sputter. It happens only a few times per year. Will the OBDII live data log a sputter like this, or will it just display it for a moment, then the error goes away?

Which sensors should I replace? CPS done already, and two O2 sensors. What's the next few likely candidates?
