E48 acting crazy. Any ideas?

[sutor623]

So I was correct in my diagnosis. The motor was acting like that because the charge coil was failing at higher rpms. It was sending voltage sporadically. Spark was dropping off of BOTH cylinders at the same time, and after running for 10-15 mins it was hard to start.

Swapped out the charge coil (and timer for good measure) and back on the water!! Just thought I'd post the resolve for any future readers. Thanks!!
