2000 200HP Ficht Running rough then completely died

[fireman_bob]

Hi,
Motor has been running well for a while (since fixing ignition coil grounding issue) until last night. While coming off plane, I noticed a slight hesitation around 3k rpm. As I went up and down in throttle over the next few minutes, the hesitation got worse. It felt like the same issue I had earlier in the season with the ignition coil grounds dirty/corroded. I headed for home and was going about 6 mph (around 2krpm) with the motor hesitating slightly, but running. At one point the motor just shut off, like the key was turned off, no alarm, no CE, nothing. Attempted to restart and all it will do is crank. I get the 4 indicator lights on the dash when the ignition is turned on, and the motor cranks but wont fire.
My question is, could running on only a few cylinders (if one or more coils weren't firing) cause an EMM to completely fail?

Start with a spark,compression check. If your problem before was bad grounds look at all grounding locations of the electronics.

Rebuilt EMM is $831.00 from DFI Technologies, they said they do about 30 upgrades and new one is 2400 from Evinrude, I know had the same problem.

Update: I did some basic troubleshooting last night with the software.
Checked all fuses - good, including inline fuse.
Safety circuit - working (pulled relay, heard it click)
Fuel - good, had fuel pump running when key first turned on
CEL - off, no stored codes
Injectors - Ran test software and was able to fire each injector (could hear them clicking)
Ignition - was NOT able to fire any ignition coil. Resistance on all coils checks out per manual
Put timing light on each plug while cranking, got nothing on any plug.
Put new battery in, still nothing on the plugs.
Concluded EMM is dead, again.
The EMM was at DFI last October for a rebuild. I've got about 20 more hours on the motor since then. Seems like it's failed once again. I hope they can help me out and fix it under some sort of warranty. I'll keep you posted.
