Recently something new started that is annoying to say th least. About a week ago, my car started cutting off unexpectedly while sitting at a stoplight.

This morning it shutter once on the way in while stuck in traffic, then a few minutes later, it cut off without warning. While still sitting in traffic. It reminds me of the fuel pump relay, so I bought a new one and installed it.

Then this evening it did it again. I have cleaned the battery terminals a few days ago, hoping that might fix it, but it had no effect.

Any idea what might be wrong? I feel it's electrical but I did wonder would a fuel filter clogged up do this?
