trouble with eng starting need help

[billsbowtie]

heres a little update. so far i have replaced the voltage reg. & ignition switch. i also fixed the frame to cab ground & eng. to cab ground. and the battery to eng. ground was loose & i fixed it. there was a 3 wire plug unpluged under the dash near the fuse box i pluged it back up. the eng will start and run when cold now without help with the wire from dis. to bat. but if it gets warm it want start back. so i will keep looking for the prolbem. just wanted to updated the ones that was interested in this tread. bill
