Update...had to ecm repaired and everything is working normal. Also installed the quadzilla adrenaline while I was at it. I am pleased with the results. Thank you guys for the advice.

Thank you guys. I'm removing the ecm and having it repaired. I will update when I get it reinstalled.

I have scanned it for codes and the only thing that showed was grid heater relay, nothing else. It isn't throwing a check engine light either. Forgive me for being a noob, but I'm not sure what the W-T ground wire mod is.

I've been having trouble with my 98.5 2500 for sometime now. I go to start the truck and it "lopes" about 10-12 times and dies. I have no throttle response when pressing the pedal while it does this. I have replaced vp44, crankshaft position sensor, camshaft position sensor, throttle position sensor, grid heater relay, I have newer batteries, also cleaned the grounds really good in the batteries as they had a little bit of corrosion on them. When I turn the switch on it takes a couple of seconds for the WTS light to come on, when it comes on i can hear what I believe is the fuel pump priming. WTS goes off and I start it and it does the 10-12 "lopes" and dies. Any help or advice would be greatly appreciated, thank you in advance. 20200428_195135.mp4
