I just put a rebuilt 355 GMC in my suburban. It boggs, then surges with power all at once. Then it dies, restarting good, then after a matter of minutes, dies again. Can you help me? New fuel pump, distributor, pick-up coil inside distributor, rotor, i've replaced everything. FRUSTRATED!

Try cleaning the throttle body plate. This is the cause of alot of problems on cases like yours. Spray some choke cleaner on itndwipe with a rag on both sides. Ifit is a TBI unit then start the vehicle up and clean it while idling, it will tend to stall out so make sure to do it slowly. Then if it also is a TBI, check te vacuum hose to teh map sensor and see if it is soft or collapsed. If it is replace it.
