If you are having problems where the engine warms up then stalls you have most likley a bad ignition module and/or a crank sensor problem. Most common items on Gm cars such as Berettas or Corsicas. They will act up when hot wen failing.

doesnt stall.when you shut off motor, and try to start again.cranks very slowly . then as engine cools down,engines cranks stronger as engine cools.runs good,when cool starts good,just not when engine is hot.

Sounds like a cranking issue rather than a running issue then. If I had to guess I would say a bum starter, possibly an alternator. These are rebuilt items most of the time as new ones would be very expensive to buy. Not uncommon for them to be bad out of the box. A starter with bad bearings can become very hard to crank over when hot, likewise an alternator unable to put out enough voltage OR amperage will cause a lot of problems including starter failure. Rebuilt starters can fail with less than 10 volts even for short periods of time. I would get the alternator tested and the starter too. I assume the battery was tested with proper tester that pulls amperage and tests for voltage drop?
