First a little info on motor and car specs.1961 Falcon 302 bored 30 over,Lunati cam488 lift 284 duration 110 lobe seperation, Torker manifold 650 Holley double pumper 69 primaries 72 secondaries 31 squirter in front 28 in back 30cc pumps.After 5 runs at the strip launching at 3700 rpm and doing good just got on the ladder and decided to launch a little higher 4000 rpm the car came out of the hole an died before the 60 foot mark I was able to restart it and get a time of 17 something luckily the guy redlighted,took car back to the pits and could find nothing wrong so when next round came, up after a good burnout I went to lauch and the same thing happened again was able to restart it but a 27 time was not good enough to win needless to say and after a .516 light. Anyhow car seems to run fine after it gets going again. This has never happened before and is hard to test on the street. All components in the carb have been checked and cant find anything wrong. What do I need to look at to solve this problem?
