Does it stall at idle or going down the hi-way? How long since a tune-up? Any applicable trouble codes? When it stalls if it cranks good but won't start, have a helper crank it while you check for spark at the plugs, use a gage and check proper fuel pressure. Check fuel injector pulse. Those are the basic checks, in my opinion. Also, you might want to check rpm signal, that comes from crank sensor. I'm not saying the crank sensor is faulty. At the moment, the problem could be almost anything, that's why you do testing. Just my opinion.
