Had this same thing happen to me last weekend. Was leading a bunch of street rods from Myrtle Beach to home. Doing 70 to 75 north of Columbia, SC, where it gets hilly, and it hit. Limped around for 50 miles or so but knew there was no way it was going to make it up Black Mountain on I-26. Removed top of carb on side of road and internal filters where fuel is delivered to bowls were clogged. Cleaned them and bowls with rag and carb cleaner. Ran like a top again. Either bad, on the road, fuel or sitting for long periods or both caused this problem. Check/replace all fuel filters, and a can of “Seafoam” would not hurt.
