2002 v6 starts then stalls

[modnarte]

After driving about 100 miles yesterday (car usually drives shorter distances...in town), stop for about an hour...car starts, put in reverse and stalls out. Tried several times, let it idle giving a little gas, got it going.

Same thing this morning, from cold start though. After driving a few miles and stopping for errand, same thing when trying to start again.

Car recently had oil change, smog check...new rear brakes and valve cover gasket tightened.

Mileage is low...>54000.

Any clues? Thanks!

If the engine idles OK but dies when the throttle is pressed may be the manifold air pressure or throttle position sensor.
