Ok guys,

Another update here. I decided last night to check the fuel filter and sure enough it was significantly gunked with debris. I assumed this was ok becuase I cleaned it out when I had the car dyno'ed in August and I have had very little run time since then.

I think this may be part of the issue for sure. I know somebody here said to check the carb for fuel so on that suggestion!

Seems a little bit different from normal fuel filter issues where it just clogs and that's the end of it, no/poor running until it's fixed...not run for 15-25 minutes then die...

I will try to test and let you know how it goes!
