vehicle was stalling then had to wait to start. shop replaced intake gasket converter and y pipe. yesterday driving long distance vehicle would just quit. wait a few minutes then it would restart. acted like a missfire of some type

Intermittent problems can be difficult to track down. Any codes extracted right after the failure? This might be a case where you have to have diagnostic equipment hooked up when the truck stalls.
