Welcome to the forum. I suggest that you use the search feature in the upper right to search for threads related to intermittent stall. After looking around on the forum, you might consider starting with the following in your diagnostic:

Overvoltage protection relay
Fuel pump relay

More experienced types may have some other, better suggestions. My similar problem (different model) went away after replacement of the fuel pump relay.
