Mystery
My friend's '98 stock vert will just randomly shut down. He will be driving, sometimes at road speeds, and suddenly the car slows and will not go above an idle. When he shuts the car off, and waits for 15 minutes, it will start and run normally. Sometimes it runs OK for a month, sometimes a few days, sometimes this occurs twice a day. Temperature does not seem to matter, although he drives it only on decent days, not in the rain etc. And he does not drive it hard, and no overheating.
He has spent hours, days and dollars in multiple shops, from dealerships, to corvette specialty shops- with no solution.
It is apparently also not throwing a codes, he says.
Anybody familiar with this problem??

I usually start with the simplest things and work down from there so, is it fuel or fire? That would be my first question...sounds like an old school ignition module problem...but the C5 doesn't have one of those... so.
STILL sounds like something is getting hot... not working... then starts working again after cool down...fuel pump? Need codes...
TAC module?

Pull the codes.
JMHO, could be ignition switch contact corrosion, crankshaft position sensor issues, main power wire loose to the starter (yep- while it's runnning- had this happen), dirty chassis grounds... or other gremlins... But only an opinion. Pull the codes... It's super fun and easy!

This is now the third exact same post you put up here on this site. How do you expect to find an answer to your question when you keep posting the same thing? Don't be so impatient, give it a chance. Now the mods have to combine three different threads into one.
