so I would say that yes is the answer

Is your "Service Engine Soon" light on?

Have you scanned for fault codes?

I would suspect low fuel rail pressure...caused by a tired fuel pump.

Before considering a faulty PCM see here for more information and diagnostic tips:

Have 1995 Chevy Blazer V6 4 3 Vortec and It Ran Ok but We Had

metal box mounted in front of coil.

only half way there if you have a tbi check the crank sensor/ cam sensor that is the first line of business on that truck if the crankshaft sensor fails the truck stops dead when you wait a few minutes the sensor re energizes and the truck will work again for a bit antiknock can cause similer problems but not while the truck is running

if this happens only in the morning after you start for the first time its the clutch on the fanblade needs replacing

test for spark at the 2 plugs

check and make sure the sparkplugs are clean, I got a hunch it could be that small back module under the distributor cap, it is very sensitive to heat.

How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

nothing ..normal low pressure at idle while hot ...but really should be thinking fresh oil change and filter soon..also what are the RPM's at idle hot in gear with A/C radio and other accessories running?
