Parts are falling off on first side when reflowing second side, have tried changing temp profiles, and ended up using tin foil. any recomendations.

I suggest tow more ways: 1. try to differ the temperaturte between top and bottom side duering the reflow process. 2. try to add some glue dots under the falling parts befor the placement/reflow process Good luck Michael

Do both sides of that board contain larger IC's and other large components or just one side?? If just one side contains large components, try running the side with the smaller components first, and then run the other side last. If that doesn't work

Assuming you are using Sn63/Pb37 solder paste, have you tried using a lower temp melting point solder paste for the second pass? For example, use 63/37 for first pass and a Bi58 compound solder paste for the second pass. If I recall, Bi58's melting

Without a detailed description of the suspect parts It is difficult to pin-point the exact solution to your process problem. However, whenever possible avoid non-value added additions to your current process. Here is the reality of the situation:
