I have owned this Blazer for 12 months and in the last 3 months it's taken to cutting out on me while driving.
There seems to be no pattern (hot or cold, idling or running at 60mph) it'll just lose power. If it's idling it'll die, but will restart with no problem or a couple of extra seconds holding the ignition on. The scariest part is running down the interstate at speed. The dashboard dials all drop to zero (as if the ignition had been turned off) then within a second it fires back up and the dials return to normal. The 'Airbag' light flashes for a few seconds too. Steering loses power and brakes don't feel good when I've had this happen while slowing for traffic lights. Fortunately, it started back up again before I reached the car infront.
I've left the vehicle with a local garage for a few days, but they couldn't recreate the problem. I don't really have the time or money to go without a car for weeks on end and this problem can happen once a month or several times in day! After the problem occurs, everything seems normal. I have no warning lights on. The fuel pump is chief suspect, but my garage don't want to run me up a large bill putting new parts in until they are sure what the problem is.
Has anybody out there come across this problem before?
