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.

My Bravada cuts or stalls out WHILE driving down the road, when it is 80 degrees or more.This has happened 4 times each time on the highway. I have spark, it just won't start till cooled down.
