why does my Mazda b 4000 it will run several miles and cut off and let it sit

What is your question?

a few hours and let it cool off and it will start back up and drive, this will happen every three day of driving it, the check engine light comes off and on, i notice before it cuts off it will starts to flutter band then dies, i try to start it back up and it will start back up and then it flutters and cuts off. could this be a oxygen sensor malfunction?

What makes this problem better or worse?

it is worse when the engine is hot.

How long has your 1994 Mazda B4000 had this problem?

a few months
