Engine stalls going over speed bumps

I don't know if it would be your problem. But a few months ago I was driving my dart and it randomly started driving funny, I was driving home so I was going to take a look when I got home. The idle changed and it ran funny in traffic. Before it did that the oil pressure dummy light started blinking. So I freaked out for a bit then remembered it wasn't hooked up and my mechanical gauge was showing good pressure. Then it died. I pulled over and looked under the hood, the wire for the oil pressure sender was grounding out the coil! So I wasn't getting good spark.

It happened after I hit a few bumps in the road that must have wiggled things around. Was a 1 minute fix and it fired right back up. I'm sure your problem is something simple too.
