Sorry, forgot to come back here and update. Called ECI fuel systems, they are the manufacturer of the tank. Great customer service, they sent me a whole new pickup assembly at no charge. Installed the new pickup. Added 8 gallons to the 30 gallon tank. Gauge showed just a hair over empty. Ran the gen for over 2 hours with the AC on in the camper. No issues. At least for now I'm going to say that it's fixed. Anyone having these type of issues, consider dropping the tank and replacing the pickup. It's not that hard a job and seems to have fixed my problem. I will be giving it a good workout over 2 trips in June and will see if there are any issues.
Over the two trips last month, we used the generator a lot. Absolutely no problems.
