Molder was 3-under through 15 holes at the Utah Energy Solutions Championship when the third round was suspended Saturday due to inclement weather.
Play was halted twice, the last time at 5:50 p.m. local time because of lightning.
Molder, who is seeking his first win, currently stands at 19-under-par and will have a four-shot lead when the third round resumes Sunday morning.
His best Nationwide Tour finish ever was runner-up at the 2002 Jacob's Creek Open Championship. He also has a third-place finish on the PGA Tour, at the 2001 Reno-Taho Open.
Craig Kanada owns the clubhouse lead at 15-under 201 after shooting the round of the day with a 7-under 65. Also looking for his first career victory, Kanada would like to earn it.
'Hopefully I'll get in that last group and compete with him (Molder) head to head,' Kanada said. 'The course is playing really short so there are birdies to be made. This golf course suits me. You have to have a finesse game and that is my game.'
Ken Duke shot a 4-under 68 on Saturday and is alone in third place at 13-under 203. Jamie Broce had a 66 and shares fourth place with Scott Parel (69) at 12-under 204.
This tournament is no stranger to weather delays. It has had at least one suspension in all but one year since the inaugural event in 1999.
