Howdy, I have an 2001 Pontiac Grand Prix

intermittent engine issue. After about 5 to 8
minutes of running it feels like the engine
"thumps" It will happen at idle or 70 mph.

Check your motor mounts and transmission mounts. They're prone to failure. If one is broken the engine/transmission assembly may be shifting and causing the noise. HTH. -Jim
