Default 1988 F250 460 driving me crazy

Hi all, I need some advice. Iím not familiar with these ford trucks. Itís an 88 F250 5 speed 460 single cab long bed 4x4. I keep getting a check engine light and the truck cuts out trying to drive it. Seems it only does it once warmed up. Trouble codes Iím getting. 82 84 key on engine off then 22 and 33 continuous memory then 12 with engine running. Iíve changed the pickup in the distributor and the box on the outside of it (canít remember what itís called) map sensor throttle position sensor the sensor on the egr valve and the computer bought remanned from the parts store. I havenít had this truck more than 6 months but all this started recently. Thereís at least some of the vacuum stuff been taken off, I assume itís part of the emissions system but the truck ran great the whole time Iíve had it until now. I have an O2 sensor and egr valve ordered. Thereís no catalytic converters. I also just replaced the high pressure fuel pump and fuel pressure regulator in the last month. I need some help here. Iím an ok mechanic but this electrical problem has me stumped and Iím tired of throwing money at it. Can someone give me some suggestions as to where to look please?
