When the engine stalled, were the dashlights showing?
When trying to restart, did the Check Engine Lamp goes off after 2 seconds?
There are 2 other possibilities that I can think of based on your description of the symptoms and best time to do test is when engine stalled and could not start.
1. Ignition switch. Slowly turn ignition key to RUN ( ON ) and while doing so, watch the dash lights, they should show without flickering. Slowly turn ignition key to START and during this time, dashlights should continue to stay on and not flicker till engine starts. If lights flickers or goes OFF while cranking engine, the ignition switch is bad.
2. Ignition coil. When engine could not start, test for sparks by pulling out a plug wire and attaching a spark plug to its end. Crank the engine with the plug held to the engine. If sparks are dull orange or none available, the ignition coil is bad.
When installing the thermostat, the ECM ground connections at the thermostat housing could be contaminated and when connected, it could be providing insufficient continuity. Remove, clean and retighten the connection to see if it helps.
