Hey guys I have a 88 mighty max it has a brand new carb, new fuel filter, new cap plugs and plug wires. When I'm driving the truck (usually when it's cold) and I'm just cruising at a steady speed 35-45mph the truck cuts out and if I continue to gas it it will stall but if I let off and wait a few seconds I can give it some gas again but only for a few seconds then it does the same. When it's warm it doesn't do it every time but just every now and then. I've had to get on the freeway before and it just has no power when I floor it it feels like it's fighting but cutting on and off. Any advice is greatly appreciated I am plain and simply just stumped
