Help Please!!!! engine wont run

I have a "72 Duster 318 4 speed. I did a very mild build of 318 with ported heads, .430/ 270 dur cam, holley 650 and street dominator intake. I converted it to an electronic ignition using a mopar performance kit with the orange box. I put 3,000 miles on the engine last summer and another 500 on this year with no issues. I was just accelerating from a stop sign shifting at about 3000 and going into 3rd i got an oil light and the car backfired a few times and died as soon as I put the clutch in. I took the distributor out and also the oil drive shaft and inspected the gears and everything else finding nothing wrong. I used a primer shaft and spun the oil pump and got good pressure. I put it all back together and tried to start it again and it sounded aweful. It sounded like a bunch of pops rather than the engine actually running and took about half throttle to keep it alive so I shut it down immediately but I had oil pressure. I thought maybe i sheared a key for the timing chain but I just took that apart today and everything looks fine. I'm stumped here and would appreciate any help :banghead:. At this point I'm thinking electrical issue. Could something trip the oil light and mess up the ignition?? Sorry for the lengthy post, i just wanted to give all the info i could
