I have been Lurking on this site for awhile trying to soak up as much as I could for this project my daughter and i have been working on and have learned allot but apparently i have fallen a little short I recently swapped a VW vans original motor for an EA82 that i had in a 90 loyale.worked well fits great with room to spare more power than the old VW motor. we have had it on the road for a few days now and have been overall happy with it. HOWEVER my daughter says it just quit on her while shifting to 3 in traffic. just shut off while moving. i have checked fuel,fire,air,fuses,all good but the timing (mechanically) was a little off the tensioners were loose so i adjusted them.now I'm thinking it must be electrical is there some safety circuit Oil or other that would account for sudden stoppage? can anyone help
