When you say you've replaced everything you need to have heat, does that mean the engine thermostat? What you're descibing sounds a lot like a faulty engine thermostat. It could also be a collapsed or blocked hose between the engine and the heater core or possibly a blocked heater core. If there is quite a bit of foreign debris in the line that has blocked the heater core you might not be getting enough flow to keep the heater core warm. Try back-flushing the heater core. Remove both hoses, turn the heater to high (you might have to have the engine running if the heater controls run on the engine vacuum) and use the garden hose to make sure that you get good flow through the heater core. Don't allow more than about 15 psi through the heater core since much greater pressure can cause damage. As for fuel pump cutof switches, most are in the trunk either clearly marked on one side or the other or behind one of the side covers. If it isn't clearly marked, you may need to refer to the owners manual or contact a dealer.
I just replaced the ABS speed sensor located on the rear differential and fixed the problem. 10$ 10 minutes.
There are two possible answers: 2/5 problems per minute or 5/2 minutes per problem. The logic behind these fractions is simple. You have two measures: 2 problems and 5 minutes. So one fraction, the first, is "2 problems" divided by "5 minutes" and the other is "5 minutes" divided by "2 problems".

I had a 1995 Dodge Ram Pickup that did the same thing - it was a blockage in the catalytic converter
It is located on the firewall side of the engine. Towards the passenger side. Just above the oil pan. (The original respondent) just replaced one on a 1991 3.1 liter. I was lucky that I had access to a lift. It was sort of a pain but I got it replaced in about 45 minutes. The bolt is 8mm. Use a 1/4 drive with a long extension.

disconnect battery cables for minutes then reconnect them, this should reset signal in computer if problem has been fixed
