Was driving yesterday and went over a road bump. Engine stalled (lost power) for a quick second along with I believe was oil and water light. I had a leak on my cab air spring so was thinking that's why it did that. Replaced both air springs got loaded and hit the road. 7 hrs into my trip, the lights came on again along with the 1 sec stall, after a road hump over a bridge on the highway. 10 mins later it did it again but no bump. Engine lost power and was slowly slowing down. I shifted to Netral and it quickly died after that. It turns over but doesn't turn. I check done this:
-Checked all fuses along battery, ECM and they are good. Changed the fuel solenoid and 4 new batteries. The ground was super lose and didn't have proper contact, so put new ground and nut and bolt. Keys are off ignition but buzzer is still there and also the warning and oil light. Any suggestions?
Had mobile mechanic come out and check for codes but the laptop would get any data from truck. He said it would connect and thinking my ecm is fried.
96 FLD, N14. Ign off but oil & warning light on. Won't turn on
