'98 Honda Accord just shuts off while you are driving along

Does it start immediaetly back up or do you have to let it sit and cool down a bit before it will restart? These are popular for internal distributor problems when they get older/high mileage.

One common cause for Honda cars is the fuel pump relay located under the speedometer.

this is a TCM (tranny brain) operated, A/T
so scan it, in this old car , it either scans with the PCM or
has its own blink codes, the TCM.
D4 means, TCM is Unhappy, please scan me for lastest news !
the engine too, is bad. but id fix that first because the tranny brain
uses,. 4 engine sensors to run'
so scan the PCM (engine brain) first. fix that first.

alldata.com has all this.. every word every step.
why not read that.?
connect scan tool $9 tools work, and scan the PCM. (ask)
get all DTCs (errorrs) and most them,, here ill also lookup
how to scan your old TCM now.
here is lots for free books on this car.

the PCM when scanned will report 10 unique DTC errors
for the transmission.
and VSS, ECT, TPS, and CKP sensors must be good or
the tranny will fault.

• Sound a little like block exhaust or exhaust system starting to fail. If not this, the spark plugs are suspected. Have an old set of plugs around that you can replace to find out. Good luck.

alternator putting out too much voltage should not exceed 15volts output

check the speed sensor,if the computer doesn't know the speed it does not know how fast you are going ,so you won;t have peak performance

check fuses under dash and under hood there is 1 for all electronics

when temp rises, it slows/stops electronics. Inside your distributor there is a ICM chip. That's usually done the trick at my shop I used to have. Oh, other thing it could be is cat converter- is there exhaust (full) coming out?
