When it is above 80 degrees.
The engine starts cutting out, then stalls. (Doesn't over heat)
After sitting, (last time for an hour & a half) it will start.
I had a fuel pump & filter installed @ 75,000 mi. Last yr.
Could it be oxygen position sensor?

Next time it doesn't start, check for spark.

Those are classic signs of the ignition module failing.
