Have you ever had changed, or at least have looked at, the cam chain tensioners?

These were an issue on the early Twin Cams.

If yours are original, I'd be surprised they lasted 30,000 miles!

After the restart, how long will it run for?
If only another 5 miles, it COULD be the gas tank venting isn't working, and you're vapor locking.

Next time it dies, remove gas cap and see if it restarts without the few hours time span.

Valve guide seals. Is it using any oil?

The valve stem seals are probably shot, if it is blue smoke-oil burning. What happens is when you shut the car off, oil slips down past the bad seals and pools around the valve seat. Soon as car is started, that pooled oil goes into the cylinder. When you shut the engine off, oil under the valve cover will do the same thing again-it will pool around the valves because of the bad stem seals. A repair manual can tell you how to replace the seals without pulling the head off. An air compressor is necessary to keep pressure in the cylinder, so the valve won't fall down into the cylinder.

First thing I need to know is where you are seeing the smoke.
Under the hood, out the exhaust pipe, or from underneath the car ??

check the spacer between the positive cables at the battery

it sounds like fuel pump may be overheating, cools down and work again...i'am sure you changed the fuel filter??? hope this helps you??

This is probably a CPS sensor.

Ouch! you've got engine coolant in the exhaust from a leak somewhere...DO NOT run this engine until you get someone (dealer is best in this instance) to diagnose ($50-125)
