This may not apply to your car. But my wife's 2003 Impala suddenly crapped out under similar circumstances yesterday afternoon.
It would restart, but then would run roughly for just a couple seconds before quitting again. The "check engine" light did not come on. And sticking an OBD scanner on it showed NO active (nor pending) trouble codes. WTF???
A quick online search suggested a failed mass air flow sensor. The test/temporary fix is to simply remove the connector from the MAF sensor. When I did that the car started and actually ran pretty well. But now the "check engine" light was now lit and the OBD scanner showed a MAF sensor fault code - expected due to the disconnected wiring.
This morning replacing the old MAF sensor with a new one has the car once again running fine. The upside is R&R-ing the MAF sensor is about a 2 minute job. The downside is the new sensor cost me about $130. But my wife is once again happy.

Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
