I have a 1999 Grand Caravan with start up problems

the entire system must be in good working condition for a vehicle to start in cold weather. Strong battery, clean cable connections at the battery, good starter, clean/gapped plugs, clean injectors, good plug wires, clean fuel filter, clean air filer, and good gas. If a vehicle sits with a partially filled tank for long periods, condensation can form in the tank and freeze. Use gas line antiifreeze in the winter.

change plug wires moisture gets into them ive had the same problem cap and rotor

Keep the gasline antifreeze in for moisture at the pumps and if not running 5W30 weight oil could make a differance as well.........Hope this helps.

If you tap the side of the dash do the gauges come back. Is the ABS light on when the gauges quit?

What does it do, if you try to accelerate when this starts to happen? If it dies,sputters or is sluggish, I'd start by changing fuel filter, and if that doesn't help, have fuel pressure tested when (if at all possible) this begins to happen. Had similar problem, winter was fine, hot weather it would die, and restart after 20 minutes or so, then go a fair distance again, then same thing. Fuel pump was on it's way out and when it got hot, fuel pressure would drop. First thing in the morning when fuel in tank and pump was cool, ran like a charm, but on way home from work, after sitting on a hot day, fuel got warm/hot, and pump heated up and that's when it started. Carried a fuel pressure gauge with me. Fuel pressure when cool, was 49 psi, and when it got hot, eventually dropped off to 2 psi. Sat for 20 minutes, jumped back up to 49psi, took off for home,then would eventually get lower and die again. Changed pump and filter, all was well. Try filter first, you have nothing to lose, and it should be changed if pump replaced later anyway.

low oil pressure . probably have a bad oil pump.

spray your distributor wires and cap with silicone spray. If this does not work you will have to replace distributor cap as it will have a hair line crack in it.

sound like the throttle body gasket leak.throttle valve or throttle cable stuck.

get a couple bottles of gas line antifreeze .. if you don't already use it and add it to the gas.

P.S. in minus 40 i don't even get out of bed... minus 23 here last nite... isn't winter grand

It can be worn distributor cap/rotor or coolant temperature sensor.
To check it leave car outside, try to activate if it is not use the hair fan and worm up the distributor cap area

If it helps replace the distributor cap/wiring/spark plugs. If it doesnot help warm up the coolant temperature sensor:

and, if no help, spurk plug area.
Also good idea in cold weather use higher octane fuel or regular with octane booster or injectror cleaner added and ask the mechenic to put winter oil (less viscous) for winter time during oil change.
Good Luck
