As I was driving myself to the yard today to get some parts for my blue 244, I was going about 45 mph? and then all of sudden I felt a light jerk and there was no throttle response at all. then all of the lights came on in the instrument panel. then it stalled and i safely pulled in to a neighborhood. i called ipd and my local dealership and asked some people of wahts going on. they said to check the no 5 and 7 fuse (good), spark plug wire connections (good) except when i pulled out a spark plug wire the copper thing came off and so i need to get in my silver 240 to get one puilled off for temp use off a b230f anyways, i tried starting it and it wouldnt fire up. did it four times and the car started finally. i let it idle for about 5 minutes and it shut right off. couldnt get it to start. so for about 3 hours i was outside (93 degrees) trying to figure out why i couldnt start it. so i checked the fuel pump relays and pushed the connections in. (are there two on an 84??) and so now it starts fine but with only 3 cylinders. what else to check because im going down to the midsommar event in kc in a couple weeks with a friend so i need everything to check out ok.

UPDATE!! i thoight it was the timing belt that was at fault but it checks out okay. checked all the spark components all is good. it will sometimes start but now it wont and if it does it will run for 5 minutes and stall. and wont be able to restart. fuel pump or intake prepump??
