See if you can borrow a data logger and see if any sensor is lazy / reacting to heat.

If it's acting like a vacuum leak that would lead me toward a fuel injector. I would run a double dose of Chevron Textron through the truck to clean up the injectors and pump.

Could even be a MAP sensor, but the data logger will tell the story.

The data logger will be your best bet.

Yea...
For a speculative guess, it could be the PCM. It runs fine in open loop and dies in closed loop...

Unkess it is consuming large amounts of oil (not likely with 285k), it is certainly worth fixing.

I vote for o2 sensor as largest contributor to problem. Almost no doubt the injectors are unbalanced at that age which may contribute.

Thanks all. A few things to check out. I would think the two mechanics would have checked these items as well, but it won't hurt to check again.

Needs Fuel Injectors replaced ?

Did Pops ever run E-85 in it ? If so, it can corrode the final end of the fuel sprayin' system...

285K miles... Perhaps that Z71 is ready for some quality relaxation time in the friendly chain link fenced retirement home for older pampered trucks..

Text Doug to get on the waiting list..

Could it be a loose nut behind the wheel?

Pull the distributor cap and see if the rotor moves any. I've seen a lot of worn out gears that can cause problems like that. I don't remember if '95 had a plastic one or not.

Distributor was replaced. How would restarting correct this issue temporarily?

It sounds like it is temp related, but the solution is in what changes with a hot restart. As others have said, a datalogger should show what is changing during the hot restart, that will be your problem.

You'd be surprised. Just depends on where it picks up the signal when it starts if its bouncing back and forth. I had an express van mess with me like that, if I turned the rotor one direction it would start and run fine. Turn it the other way just a little bit extended crank and run like crap.
