2000 TJ, 4.0L, auto, 100k -- the thing cuts out suddenly, with no warning, no sputtering, no nothin' . Happened three times so far; the first two times, I coasted the jeep to the roadside, and it re-started. This last time, it wouldn't start.
It cranks OK, and there's pressure in the injector rail.
I couldn't get it to throw a code on the odometer.
Diagnostic suggestions ?
