Check engine light came on - folivier - 07-22-2013

A couple days ago when driving I had a yellow check engine light come on. By the time I quickly stopped on the shoulder the light was already out.
A few minutes before all of the gauges on my VMSPC went to 0.
Here is the diagnostic log from the VMSPC (the Prodriver doesn't have any errors):

ENG SID 49 4 Injector Cylinder #19 Low Voltage 7/20/13 10:43
ENG SID 65 8 Heated Oxygen Sensor Frequency Error 7/20/13 10:43
ENG SID 48 7 Injector Cylinder #18 Not Responding 7/20/13 10:43
ENG SID 48 1 Injector Cylinder #18 Low Reading 7/20/13 10:43
ENG SID 67 2 Ignition Control Timing Signal Invalid Data 7/20/13 10:43
ENG SID 56 2 Auxiliary Output Dev Driver #8 Invalid Data 7/20/13 10:43
ENG SID 67 4 Ignition Control Timing Signal Low Voltage 7/20/13 10:43
ENG PID 256 0 Parameter Request High Reading 7/20/13 10:43
ENG SID 69 8 After-Cooler Coolant Temp Frequency Error 7/20/13 16:16
ENG SID 48 2 Injector Cylinder #18 Invalid Data 7/20/13 16:16
ENG SID 68 5 Secondary Turbo Inlet Pressure Low Current 7/20/13 16:16
ENG SID 48 0 Injector Cylinder #18 High Reading 7/20/13 16:16
ENG SID 55 1 Auxiliary Output Dev Driver #7 Low Reading 7/20/13 16:16
ENG PID 506 4 UNKNOWN COMPONENT Low Voltage 7/20/13 16:33
ENG SID 48 9 Injector Cylinder #18 Abnormal Update 7/20/13 16:33
ENG SID 56 0 Auxiliary Output Dev Driver #8 High Reading 7/20/13 16:33
ENG SID 48 4 Injector Cylinder #18 Low Voltage 7/20/13 16:33
ENG SID 50 9 Injector Cylinder #20 Abnormal Update 7/20/13 16:33
ENG SID 48 0 Injector Cylinder #18 High Reading 7/20/13 16:33

So what happened? The engine never lost power, oil, coolant, etc. were all ok, temp ok.
Maybe the DDEC went stupid for a minute? But no error codes in Prodriver. Occasionally on the VMSPC the battery, coolant temp, and a couple other gauges will go to 0. I talked with Silverleaf and the tech couldn't figure out why this happens.
I can live with the VMSPC occasionally going to 0 but want to make sure there is nothing wrong with the engine.

Bad connection or ground.

I would check the ddec connections, clean them, and reinstall. Check engine grounds too

I'll do that when we get to North Fork, ID for a couple weeks.
Hate to do it the day before a trip.
Thanks Richard.
