alright, i have a viair 400 on a 5 gal. tank w/ a 110/145 ps, had this for about 6 months with no problems until the last week or so when i air up my truck the comp has been taking way longer than usual to turn on. it usually comes on immediately after i air up the front and back since i only have 5 gal. but tonight it wouldnt turn on at all, i kept dumping & filling over & over to try to get it to come on but it wouldn't. i was at work so i went back inside and when i came back out the comp was hot so i knew it had run and this was like 30 min. later. so luckily i was able to get the truck up to drive home. could this be my comp dying, pressure switch or what?
