Okay this can be a few different things. I would first begin by checking for a restriction in the exhaust system. Many times these vehicle will get a plugged up exhaust causing it to stall out when hot. If you remove the front O2 sensor when it will not start and it will start chances are the catalytic converter is bad. If exhaust is clear test 2 get some carb or starting fluid and spray into the carb when it will not start. If it will run off alternative fluid this indicates you either have a bad fuel pump or the carb float is sticking closed. If that is not the issue I suspect your vehicle is losing spark this can be caused by the coil but that is very unlikely the first two are much more common on your vehicle.
