How does it stall in drive? Stumble and die? If you hold the RPM up will it keep running? Does it instantly quit and just won't run? Need more information? With it running in park wiggle all the harness connectors on the back of the engine is a big 21 pin connector check that one. If it stumbles or quits when you wiggle these things thats most likely where the problem could be. Good luck!!

Glad I could help. The wire was happy in park but when you put it in gear the engine moved to break the connection.
