Ok, here's onething that happened to me many years ago and I've never heard of anyone having a similar problem.
It was a 1966 Chevy Caprice 396. The engine would start and run normally then, for no apparent reason, it would lose all power but still keep running (at an idle); this happened at all speeds up to 65 mph. I would shut off the engine and restart it after a few minutes. The engine would run normally for awhile and I would repeat the process. The problem?
Dropped the gas tank and found a 2 foot piece of plastic (looked like
2-inch wide tape) that was apparently being pulled up to the sock, restricting the fuel. I was told that the plastic came from the inside of a gas pump hose. Removing the plastic fixed the problem. BTW a co-worker of mine found the spring from a gas nozzle in his tank after it wore a hole through the tank from rolling around.

The pressure was checked before started and after it dies. I replaced the fuel pump about a year ago so I was thinking (hoping) that wouldnt be the deal. The truck is stranded at my brothers house about 45 miles away so by the time i get off work and drive out there I only get to check a few things before it gets dark.

I checked that it is getting fuel and then replaced the ignition coil without any luck. Any ideas? Thanks. Start by checking the fuel pressure, you may have a pump going bad as thye can act like this.

Fuel pressure checks out. It really acts like it looses fire. After I put the coil in it , it started and ran for about two minutes on idle then died, started right back up and ran for another three minutes and died again and would not restart. =A0 Lately, its had a clattering noise i have been trying to chase down, sounds like timing is off when accelerating which makes me think maybe the elec. spark control module or the ecm itself may be going.
