I have a 1992 V6. The issue is that when I drive it for about 10 blocks it shuts off and then I have to wait about 30 mins or more before it will run again. I have replaced just about everything you can think of and about to junk it. but someone told me it might be a manifold leak. But before I invest anymore money into it, I would like to know if anyone has had that issue and what fixed it.

I am now thinking one of two things: there is a crack/leak in the CAI (custom air intake) or there is a leak in the exhaust manifold

 

have you checked spark when it wont start?

 

Great place to start. Our cars have a problem with heating up the ICM(Ignition Control Module) and when that happens, it craps out and doesn't put out a spark anymore.

Mine did this to me one day because the sahft bushing on the distributor went bad and heated up the plate the ICM is bolted to, then the ICM heated up and quit, I would have to wait for like 5 minutes for enough heat to dissipate until the thing would start again, but it would just die a couple of minutes later.
