Engine stalls

[gafitanu]

I have a 92 Bonnevile. The engine is fine, I just had it emissions checked and it runs clean, no oil burning.
Recently it stalls while running on the highway or it doesn't start for 5-10 minutes. If it happens on the highway I pull over (quite difficult without power steering and brakes) and after 5-10 minutes it will start again. Meanwhile the engine cranks but it doesn't fire.
This happens after a longer drive or after sitting in traffic. I believe that it is of electrical nature because the engine is completely dead not even one or two cilinders trying to fire and I hear unburned mixture exploding in the exhaust pipes. Yet, I still can not dismiss the fuel system completely. Anyway I changed the computer, the ignition module and the coils separately and together and the problem is still present. It's true I switched the computer, the ignition module and the coils with other old ones. I don't get any "check engine" light code. I hope is not a wire somewhere.
Other than that what could make an ignition system shut down like that? The crankshaft sensor? The camshaft sensor?
Anybody knows anything about this?

Thanks a lot.

It fuel injected.
