dead o2 sensor?

could be an issue with a faulty fuel pump or injectors.

if it was injectors or pump wouldent it stall cold too not just when it was warmed up? thanks in advance guys

probably, but Im just throwing ideas out there. It might be that once the car has heated up there has been enough of a drop in fuel pressure that the car happens to shut off when the car is warm, not because the car is warm. Again, thats just my theory. Does the car restart after stalling or does it have to cool down first.

You should also do the pedal tap to retrive any fault codes, that might reveal your problem.

Sounds like plugs and wires, work good cold and stalls warm. If the insulation on any of your plug wires is wearing thin (likely where 2 are rubbing together) they will short out when it heats up...goes for any car...how bout an update what was wrong.

e36, 325 does not have plug wires. You could have an idle valve sticking. You can try removing it and cleaning it, if you feel like diving in.
