The 428 has the Comp cam 294H cam with roller lifters, could the roller lifters be failing when the car is at idle(bleeding down), weak coil,...etc? The motor was running fantastic before the problem started, I was told that hydraulic roller lifters start to fail at around 3000-5000 miles (I have 4700 since the rebuild). I havn't had the chance to go over the motor and planned to do it this weekend, anyone had a similar issue?

As a general rule, hydraulic roller lifters will go 100's of thousands of miles...
Solid roller lifters are the ones you have to keep an eye on.
A 294H cam is a flat tappet cam, so you don't have roller lifters at all.
