With all that detail, you've narrowed it down to, oh, about 1,000 possible things.

I'm not going to list 1,000 things (others might). If you want a useful answer, consider telling us more. Like, it starts every time? How long does it run? Did you "just" complete the trip, or did something happen after you pulled into your driveway?

It starts & runs 10-15 seconds then dies -exhaust does sound restricted- had new exhaust @ 175000 -I'm racking my brain & other than plugged cat converter or t-belt failed
- I don't know-
Nothing occurred when I pulled in driveway. Other things checked for included:
No creamy appearance to oil on dipstick or in radiator -
Engine has 279,000 -had major over haul - rings, oil pump, new t-belt, water pump.
Complete tuneup b4 trip -plugs/ wires/ cap rotor, etc j
Thanks all

Test the o2 sensor? Maybe evenn get under there with something to smack converter if u think its restricted .

If you have a problem in the VAF/COR circuit, the fuel pump will shut off after you let go of the key. A few seconds later it will die. Very easy to check; jumper FP to B+ on diagnostic port, which forces pump to run with Key-on.

running- I eliminated by causes til i remebered I had filled tank on way back to house & believe cause is due to fact station middle of fuel delivery- thereby kick
