My 2005 Suburban has been slow to start for the last month or so. If I turn the key to the start position and off again a couple times first it usually starts right up. The problem is that every 3rd or 4th time I start the engine, the clock resets itself to 12:00. Nothing else seems to happen. The radio and XM stations stay set in memory. The clock just resets. Do I have two problems here? One fuel related and one electrical? Thanks for any input.

i would suggest having your batter and charging system checked. autozone and most other car parts shops will do it for free
