1998 silverado 4x4 loss of power

[Greg reid]

Hey everyone i have a 1998 silverado 1500 4x4 with 5.7.

Ive been having issues with power loss and sputtering out. Ive had a full tune up done:plugs,wires,cap,oil change, fuel filter oil filter air filter replaced, all four o2 sensors replaced and both cats replaced has a new battery week old alternator is great. The truck purred like never before for about 200miles then boom loss of power all gages come on. She fires back up no problem no gages on still purrs then power loss again. Both neg and pos cables have been replaced and still having the same issue. Any thoughts

Fuel pump pressure at rail? Fuel pump failure or electrical connector to fuel pump would be two fun places to start looking.

Check your injectors. How many Mikes any engine codes?

I have seen instances where the ignition is faulty and basically shorting out the whole instrument cluster and shutting the truck off.

 

Chevy had recalls pertaining to this in other models.
