Default P0351 - Primary/Secondary ignition malfunction

Yes it runs, but it falls on it face when coming to a stop, or at a stop sign/light.

Will it start right back up when it quits?

Possibly a loose wire somewhere..... Coil gets power via the ASD relay, PCM controls the ground.

It usually starts right back up. Sometimes take 2-3 tries.

That's gonna make it fun to troubleshoot..... Need to find out what's missing when it won't start, verify power TO the coil first... (while cranking.)
