Stalls after 15 minutes

There is one thing to note - the exhaust pipe is partly separated from the exhaust manifold. This is directing the exhaust toward the fuel line and air line. Undoubtedly this is not good, but I"m not sure how significant this is.

I"ve had a few ideas on the matter, but would appreciate any suggestions.

Thanks,
Greg

Thanks all for the advice. Looks like I'll check the fuel system first, then replace my coil.

I assume you're talking about blockage in the fuel line, and not the man peeing ;)

A failing coil often takes about that long, sometimes a failing condenser, but condensers in my experience recover less often that coils.

Another failure with that time constant is a plugged gas tank vent. Often the gas tank cap does that venting problem and modern unversal replacements don't vent. When it starts to stumble, loosen the gas cap and see if it recovers.
