who did the timing belt job? take it back to them, which should be under warranty if they are a reputable shop.

possible a loose connection in the ignition system or worse. check all plug wires are tight against the rotor caps, and all connections are tight and properly positioned.

could it be a faulty ignition switch?

Check the battery and connections as well. Sometime back I came to a hard stop and the engine stopped. I was WTH! Started right up and ran without issue then on but it bugged me. Turned out that under the positive connector was a heavy coating of corrosion. There was tiny bit of clear post to contact. Even though the battery is bolted down, hard forces when cornering or stopping can cause a slight shift. If the connection is iffy, that can break electrical contact for that moment causing the car to shut off.

Maybe a connector was not connected tight and fell apart.

I had a similar problem with my '92. It got so bad, if you hit a bump in the road just right, it would cut off. It would restart but sometimes took minutes of trying. I found the trouble was with my main (left of column under dash) fusebox. I could wiggle the large harness going into that fusebox and hear relays clicking underhood. I replaced the entire fusebox but did find loose fuses in the old box caused the trouble. Problem is now gone.

Glad that was simple.
