vapor lock

[bossrod]

I think I experienced a vapor lock the other day. Truck just shut down, started briefly and then shut down again and wouldn't refire. Went out today and it fired right up. I'm running headers on the vehicle and was in some bumper to bumper traffic just prior to the shut down. This is the only time it has happened in the short three weeks I've had it back on the road. Were there any shields on these trucks, 72 C-10, over by the gas line? Any suggestions on how to make sure this doesn't happen again? Would greatly appreciate any ideas as I have already searched the forum for answers.
