alright its your coil more then likely...try disconnecting your batt..when i ran my drag car on the street i had the same shit happen to me..the coil was to close to my headers(car was a 93 camaro with over 700hp) and the coil got hot and it killed the spark..i had every thing in the world but not enough of a spark out put to crank the engine over..i parked the car dis the batt and then came back the next day and connected every thing and it fired right up..i had a blaster coil 2..
