My 59 runs perfect after the rebuild of the stock engine and carb. HEI ignition added I have driven 500 miles in the last few months with no problems until last week.
Drove about 20 miles on a hot afternoon and when I let off the gas pedal to slow down for a turn, the engine died and would not restart for 30 minutes. Sure seemed like it was not getting any fuel to carb. Choke did not help and finally 30 minutes later it ran good al the way back home. Now the last two times I have driven it more than a few miles AND ONLY WHEN I LET OFF THE GAS PEDAL, the truck dies and won't restart for about 10-20 minutes with no hint of gas. The letting off the gas pedal has me puzzled?
What do you think? Does the letting up on the gas pedal and dying then indicate a carb issue created by the sudden loss of vacuum or sound fuel pump related. There is no stumbling or missing indicated at all before this happens. De-celerate and she goes dead for a while....float? It has been hot.... vapor lock?
