Engine, Fuel or FI problems, spitting and sputtering again Options

back in January I made this post:

I have been driving quite a bit since then, even took a 6 hour round trip day ride to Knoxville. My guess it 4 or 5 tanks or about 1800 miles and no issues.

Same thing happened today... Driving home from work on the interstate, MPH at 80, revs about 3400. Again, going up a long low hill, not far from my exit. I could feel some spitting and sputtering.

The VDO CHT ring under #3 started heading down. Dropped to 200*F. When I exited and took my foot off the gas, it died. Started right up and I made it home braking with my big toe and gassing with my little toe.

This time, I have a 1/2 a tank of e10 gas (not positive on that). So it is not running empty as hoped last time. Fuel pressure was at 40 on the engine bay gauge.

Other suggestions last time were the filter. I am going to remove that today.

With the #3 temp as it is, I might should start there. I will try my induct timing gun on it to see about spark. Need a noid light for the injector. and i'll take a look at the plug.

I'll remove the disty and take a look. But #3 seems to not be firing and generating heat.

I'll update, but any other ideas?

Thanks,
Clark
