engine runs about 3 miles and stops running
1960 corvette has been in storage for 30 yrs. I got it running, it starts great, will idle for an hour but when I take it on the road in 3/4 miles it quits running. I'll let it sit for 1/2 hour and it starts right up and runs for another 3 or 4 miles and we go through the same thing again. Any suggestions?
