I presume that by “Stop”, you mean that the engine shuts off.

This could be a ignition module, or a crankshaft position module that is faulty.  
Sometimes this is heat related and the module shuts down.

The problem might be with a faulty crankshaft position sensor.

If the computer loses the signal from this sensor, the computer thinks the crankshaft isn’t rotating.

The computer then see’s no reason to operate the ignition and fuel systems, and the engine shuts off.

When the engine stops try checking the fuel pressure at the schrader valve on the fuel manifold it looks like a tire valve and you can press the center valve pin to see if there is any fuel pressure. This could help in determining if there is a fuel or electrical problem. My experience was a bad fuel pump when the engine died.
