ENGINE RANDOMLY STOPS

2001 Oldsmobile Alero

Electrical problem
2001 Oldsmobile Alero 4 cyl Two Wheel Drive Automatic 87000 miles

Engine randomly stops as if turned key off. No dash lights elluminated, ie. Check engine, security, oil, no buzzers, etc. After a short wait, less than ten minutes, engine restarts right away.
Fuel guage indicated 1/4 to 1/2 fuel remaining.

Engine runs and sounds fine. No fuel smell, hot oil, antifreeze etc. Only warning light is tire pressure. There is a reel slow leak front left tire, add 10 psi every week or so.

Fuel pump replaced 2 - 3 weeks ago. Swapped fuel pump relay.

Engine randomly stops as if turned key off. Next time it does it immediately check for fuel and spark one of this is gonna be missing.

Or you can do this hook up a fuel pressure gauge and monitor the fuel pressure-if okay then start checking the ignition system the coil's primary and secondary resistances for a start
