1990 Dodge Ramcharger turn key no power

Hey I replaced the transmission 2 days ago , took it out for a couple test drives performed flawlessly . I took it out today and drove it around for about 20 mins and pulling up to my drive way it stalled out . turn the key to the on position and nothing . the interior lights , horn , headlights , tail lights all work but the radio and any sign of ignition . I replaced the battery because it was old and I replaced the starter relay and still turn the key and nothing no dash lights or any sign of life . I would greatly appreciate any help I can get thanks .
