It's either going to be electrical (spark) or fuel. I doubt there it's a air problem. It's a process of elimination. I'd begin checking the spark condition first. It's easiest and can be accomplished with an HEI. The coil can be checked with the HEI also.

It was electrical the alternator was testing good but was not putting out enough so replaced alternator and it fixed the problem thanks for your help.
