I have a 1994 C1500, 5.7L with 4L60E and dealing with a gremlin. Most drives the truck starts and runs fine with no issue and what used to be a once in a blue moon issue is starting to happen every 3rd or 4th drive. What happens is the truck has a momentary loss of power, less than a second but enough to jerk me forward a bit. The SES and Brake light will both flash and the speakers will pop and crackle. This seems to happen most often when I am pulling away from a stop, it also really doesn't like it when I am reversing uphill on my driveway, if and when that happens while reversing its not momentary and the truck has a bouncing idle. When the truck is at speed, no issues, runs smooth.
There are no codes. I have checked all grounds and battery connections, nothing is loose. It had Cap/Rotor/Plug/Wires replaced about 12k miles ago. I don't 100% trust the fuel pump and I know the tank has a broken baffle, but I don't see how that would cause the speakers to pop.
Looking for ideas on what system I should be inspecting or any hidden grounds/connections I should check.
