Loss of power and miss

[clm15]

We raced last night,and in the feature about lap 6. The car picked up a miss and on the restarts it bogged. Then about lap 10 lost power to where it would idle but miss when i gave it some gas.
We think the battery is junk,we had to push start it for the feature? Was told the MSD takes alot of volts to run. I hope its just the battery?
Anyone have this problem! what else could it be?
Thanks fellow racers!

If the battery was dead enough to have to push start it, why wouldn't you try the simplest thing first? Put a good battery in it and then try bit again..KISS

well the battery checked out a ok. (took it to auto zone) The master disconect was the problem. With the engine running,we wiggled the switch and cables and the engine would shut off. Thanks to all,If your switch is more then a year old you mite want to replace it. Good luck to all.

You may have wiped your cam out, check the pushrods, rocker arms etc
