Engine jerks once while driving, MIL illuminates, begins to violently shake while in gear.

This is a 1995 SHO MTX. I'll be driving along just cruising and what I stated in the title will happen, when I pull over and turn it off, it'll refuse to start for a few minutes. The starter still cranks, it just won't fire up. I'm a little cpueless on this, the shaking is similar to what happens when the vacuum line under the throttle body has a bad leak, but I replaced that recently.
Edit: when I popped the hood to check codes I smelled fuel. I couldn't get any codes even though the MIL was on. I'm checking for fuel leaks this evening.

please pull the codes and report what they are.
then we can help you. now we can just speculate.

My guess would be a leaking water pump that drips on the crank position sensor.

Use a dentists mirror to get a look at the weep hole at the bottom of the water pump snout, that is right after you pull the codes.

The check engine light should always have a code associated with it.
