Engine loses power and shuts off in warm weather above 60 degrees. Replaced ignition module. Can turn off then crank right back up run fine for a few minutes.

Do a running check of fuel pressure when this problem is occurring, swap out with a known good ignition coil. It could also be possible that the ECM is at fault. It is going to be difficult to determine what is being lost to cause the stall, since it happens so quickly, and restarts.
