Stalling problems

I have a 92 F250 with a 351w the problem is it will run for 10 to 15 minutes and then stall at that point we lose communication with the computer.If we wait a few minutes it will start and run but stall again when it stalls it will burn real rich then stall.It will run about the same amount of time each time it runs.

What do you mean by "lose communication with the computer"?
Have you checked for spark when it shuts down?
I have not heard of a Computer going bad this way I would think more on the lines of a bad MAP sensor if you still have spark when it shuts down.
The MAP sensor may also have the vacuum hose off or a leak in it.
