Question about 1998 Chevrolet Astro

2000 Chevy Astro Van while driving just stops running

I have a 2000 Astro Van w/approx. 115,000 miles on it. The vehicle runs good and strong but on occasion it will just STOP running. Sometimes it will just quit, sometimes it will be missing before it quits.  It can go for days or weeks at a time before this happens.  I have had a full tune up, plugs, new wires, rotor, coil and fuel pump and filter along with a new relay for the fuel pump. Once the van stops running it can take 10-20 minutes to get it started again. Looking for anyone to give me a possible clue. My mechanic says it is something in the ignition system but of course nothing shows up on the diagnostic computer shows up other than there is some kind of occurrence which brings the check engine light on.

    Thank you, for the advice on changing ignition module, I have had it changed and now I will wait to see if the problem goes away. in the past after an occurrence it could go for days or even weeks before it would happen again, so now I'm back to the nerve wreaking waiting game to see if this works

    Ok lets try taking the egr valve off i done some reading and it said you should be able to clean the egr valve that means take it off and use some carborator cleaner and spray where the plunger is to get the plunger to go in and seal properly. Let me know what happens this should be a low cost fix.Mean while i will catch up on me studying
    God Bless you Greg

Hey I had my rotor and all that stuff replaced on my 2000 astro van, Intermittently it would not run, The problem was I hit a puddle one day and water flew up on top of the roter like 3 drops, it created a trace( it was arching) Thats why it was intermittent.Take a look at the cap look for like a discoloration on it clean it and put it back on.Sounds too easy but remember I had all new parts too.

Engine Stalls When stopped and in Drive

Question, did you replace the throttle body, or clean the throttle plate, it will carbon up and block air needed for the idling speed to be correct. Also check for vacuum leaks, as the older vehicles didn't have good vacuum hoses. Good luck
