If it hasn't been done yet, I would recommend inspecting/replacing the fuel pump relay and checking the fuel pressure regulator. Could also have been a spot of bad gas.

Ha ha. No problem, I said both - but I installed the ac delco flex fuel.

Good suggestion. I will replace the relay. Easy enough. I did look at the regulator. Not sure how to troubleshoot that though.

This forum is awesome. Thanks all.
Standard fuel pressure test, making sure it's not letting the pressure leak down.
Also run the engine for a little while, turn it off, then pull the vacuum line to the regulator. Check the vacuum line for fuel. Watch for two or three minutes (be patient, it can take a little time) to see if any fuel comes out of the regulator's vacuum port, which would tell you that it's leaking internally.

Well, the fuel pressure regulator checked out good. Replaced the relay, checked wiring and disconnected/cleaned/reconnected numerous connectors. Nothing obvious. The Tahoe is still running great. Took it out on errands a little while ago and made several stops. No issue. I hate intermittent issues. If I'm lucky maybe I stumbled across the issue in one of the connectors I cleaned. I will keep you all posted. Thanks again for the help.
