intrmittent problem 2010 wrangler

[jjtec]

2010 4 door wrangler. Intermittent (6 times since new) pull up to a stop sign and it refuses to take the gas, sits ans shudders like it is way out of time. shut it off and restart it and it is fine? may be weeks between problems. idle seems to drop from 750 or so t0 450 right before it happens. runs great all other times and has only had the problem from dead starts? no codes and dealer cannot find the problem.

Thanks
