Ok here goes, 1992 B2600 4x4 5 speed

when i crank the truck, it will idle fine, when you give it gas, there is a short skip as the RPMs rise and then when they get high, the truck cuts out and falls back to idle, if you hold the gas peddle steady, it has a rithem, vroom vroom vroom , as soon as the rpms get high it cuts it back to idle , if you hold it long enough it will work into a small bit where it will idle up wide open and stay there for maybe 15 seconds then cut back to idle and go through it again, ive replace, plugs, wires, cap, rotor button, ignition module, and coil. I think it is a sensor causing it, or either the ECU. Please any help. Ive put alot of money in this thing and still aint got nowhere, im lost as to what else it could be.
