Thanks for opening this thread and your contribution is appreciated.

Bought new '98 LXSedan. 122K miles.
Driven locally, 20 +/- miles ea./4-5 days/wk by retired parent.
All regularly scheduled maintenance/worn part replacement performed.

RECENT CONCERN:
Engine shut-off and power steering loss during slow down/complete stop (most often after hill descent) at intersection.
RPM drops suddenly below idle.
Sometimes/not always with AC running on low fan speed. Afternoons 80s outside temp.
Intermittently, now - most recent (3) occasions during one 1/2 hour, suburban start/stop travel.
ALWAYS immediately restarts & proceed.
Air filter new. Housing removed and throttle body cleaned & torqued nuts.
VIN# not among ignition module Honda recall.
Key jiggle test did not replicate.

Honda dealership tech claimed 4 test drives around the block - no stalls. No precautions undertaken.

Fuel pump/filter/bad gas issue observed by anyone 1st diagnosis?

Any suggestions to provide my "not-Honda-dealership service" mechanic prior to scheduling appointment?

Cheers,
Jim

If its temperature related, then the temperature sensor should be tested. Make sure to use OEM sensors... it's not worth the headache to save $20 trying to use an off brand clone.

If the gauges are dropping before the engine stalls, look at the charging system.

Is this a case where the IAC valve is not operating normally? Any codes?
