1987 corvette shut off
Hello I need help my 1987 corvette just shut off on me while driving on the freeway everything else worked but the motor just turned off on me gauges and cluster were still on I'm about to change the starter on it because when I tried to start it it would make a nasty grinding noise but what I want to know is why did the engine just shut off on me though so that it doesn't happen again?

..... Do the basic troubleshooting ... Fuel , Air , and Fire at the right time in the right quantities = running engine ... look for spark , check fuel pressure , clear the coyote from the intake , and make sure that there are no rods hanging out of the side of the block ! .....

With the engine having shut down on the freeway is it correct to assume that the car is someplace where you can work on it now?
Are you fairly competent at working on your Corvette? How long have you owned it? What happened that led up to the engine shutting off on the highway?
Do you possess the tools needed to check your fuel pressure on the fuel rail at the Schroeder valve on the passenger side near the rear of the plenum? Has the car had any issues lately PRIOR to the highway problem? Longer than normal cranking, anything?
When does the the starter make this "Grinding noise" all the time, once in a while or only after the highway event?
Is the car a manual or an automatic?
Does the engine turn over now that it has cooled off?
Did you get any codes or check engine lights when the problem happened?
What does the oil look like? Is there enough of it? How about coolant?
It would really help us if we have as much information about this car as possible for us to be able to help you. Answer the questions above and we can make some headway hopefully!
Good Luck and lets help you figure out what is happening with your 1987!

The security system, VATS, does get flaky eventually, all too often. Pretty sure it will shutdown ignition if tripped, among other things.
