Car stalls while driving, it will start to shudder before shutting off sometimes if I press the gas when I feel the shudder coming on it will keep going. Usually will start back up within 15 minutes but, there has been times where it won't start. If I keep it moving at about 80mph it doesn't die. I have taken it in but the diagnostics only shows the symptons not the cause. Something is shutting it off but don't know what. Recently put in a new computer, fuel pump, fuel regualtor and igintion modular. This did help but it still shuts off.

You need to find out what your missing, when the problem occurs. When the problem occurs, if it cranks good but won't start, have a helper crank it, while you check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure. Any applicable codes? How long since overall tune-up? You have to do a little testing,you know, give us a direction. Stalling could be caused by just about anything? I'd start by checking spark and fuel, go from there.
